      Allow CPAN to index Script_Run, Atomic_Script_Run, since they made
      it into a production release.

      Allow {,3} and { 0 , 3 } as quantifiers, requiring at least Perl
      5.33.6. Previously these parsed as literals. This parse will be
      retracted if it does not make it into 5.34.0.

      Correct (I hope) detection of \K in nested assertions.

      Variable-length look-behind is version 5.029009.

      Look-behinds quantified longer than 255 characters are an error, and
      are made into unknown tokens or structures. I ended up refactoring
      the PPIx::Regexp::Token::GroupType class initialization for the
      latter two changes.

      Recognize wildcard Unicode names (Perl 5.31.10).
      Try to get correct line number in derived PPI. This is done by
      injecting "
" as needed. The initial #line directive becomes "#line
      2", but is suppressed if I need to generate line 1.
      Improve normalization of content for ppi(). This involves the
      un-bracketing of things like ${foo}.
      Deprecate new() argument postderef. At this stage it is only
      documented as deprecated. In the first release after October 1 2020
      it will warn on the first use. Eventually it will be retracted, and
      postfix dereferences will always be recognized. This is the default
      behavior now.
      Add dump argument/option 'short' which, if true, causes leading
      'PPIx::Regexp::' to be removed from class names.

      Add index_locations option to PPIx::Regexp->new(). This defaults to
      true if the regexp is specified as a PPI::Element object. The
      locations are consistent with the containing PPI::Document.
      Add methods location(), column_number(), line_number(),
      logical_filename(), logical_line_number(), and
      visual_column_number() to PPIx::Regexp::Element. All return undef if
      the locations could not be determined.
      Add method statement() to PPIx::Regexp::Element. This returns the
      PPI statement containing the regexp element, or nothing if none.
      Add method is_matcher() to PPIx::Regexp::Element. This classifies
      objects as to whether they actually match something in the target
      string. Possible returns are true (they do), false but defined (they
      do not) and undef (no clue).
      Add methods first_token() and last_token() to PPIx::Regexp::Node.

      The PPIx::Regexp->new() 'parse' option is now fatal. This selected
      either string or regex parse. I consider the string parse a failed
      experiment. This is the latest step in removing it in favor of the
      PPIx::QuoteLike package.

      It's still a PPIx::Regexp::Token::CharClass::POSIX::Unknown (and
      therefore an error), though.

      Support proper version for qr'\N{name}'. Until 5.29.10 this
      construction failed to parse because it did not interpolate. But
      PPIx::Regexp blithely ignored this detail. As of 5.29.10, something
      like m'\N{LATIN CAPITAL LETTER L}' matches identically to m'L'. So I
      implemented introduction as of that version.
      Have explain() recognize Unicode property wildcards.

      Empty \p{} should be an error.
      \x{} and \x{ non-hex } should be errors under "use re 'strict'"
      \o{} should be an error
      \o{ non-octal } should be an error under "use re 'strict'"
      Support wildcard Unicode property values. These were added in
      Add eg/find-variable-length-lookarounds
      Add convenience method extract_regexps(). This is a static method
      on PPIx::Regexp that takes as its argument a PPI::Document and
      manufactures PPIx::Regexp objects out of anything that parses to a
      regexp of some sort.
      Don't run illegal character tests before Perl 5.18 unless we're
      author testing, because they are noisy. I think the issue is not the
      Perl version per se, but the version of Unicode; Perl5180delta says
      it shipped with Unicode 6.2.

      Only standalone graphemes and non-characters allowed as delimiters
      starting with Perl 5.29.0.
      Non-ASCII delimiters started working in 5.8.3, so that is what
      perl_version_introduced() returns for them.
      Collateral with all this, accept word characters as delimiters, but
      only with at least one space between the operator and the expression
      -- that is, 'qr xyx' is OK, but 'qrxyx' is not.

      \N{} now parses as the unknown token, not NoOp, regardless of the
      setting of 'use re qw< strict >;'. \N{} became unconditionally fatal
      in 5.28.0 (5.27.1, actually). The policy when the parse changes is
      to use the most-modern parse. Hence this change.
      As a side effect of this, the unknown token's explain() method now
      returns something -- normally the associated error.
      Add method remove_insignificant(). If the invocant isa Node, this
      returns a clone of the invocant with non-significant elements
      removed. Otherwise it returns either the invocant or nothing.

      value of the argument is 'guess' or 'string', the warning refers to

      Prefer /[0-9]/ over /\d/ for numeric checks. The latter can match
      non-ASCII digits.
      Explain the negated POSIX character classes. Also tweak some of the
      asserted explanations -- mostly for readability and parallel
      construction with the negated explanations, but it turns out
      [[:digit:]] is NOT equivalent to [0-9].

      Allow ->asserts( 'a*' ). This modification actually allows wild
      cards in asserts() on all match semantic modifiers, but it is
      probably only useful in the case of 'a*', because that is the only
      one that can be doubled.
      Explain grouping structure as 'Grouping', not 'Capture or grouping'.
      Caret modifier was not turning off /n. This was complicated by the
      fact that (?^) was introduced in 5.13.6, but (?n) was not introduced
      until 5.21.8. The solution was to include -n in the expansion of the
      caret if and only if /n had been seen in the scope of the caret.
      Recognize caret in /(?^)x/.

      Support removal of unescaped literal left curlys after left parens,
      which was deprecated in 5.27.8. No actual change in output yet,
      since deprecation is not tracked, but the perl_version_removed()
      logic is there.
      Add next_element() and kin. These are analogous to next_sibling()
      and kin, but will cross over from content proper into structure
      (beginning and end delimiters, etc) and vice versa.
      Correct requirements_for_perl() for impossible regular expression.
      It now returns '! $]' when the components of the regexp are valid, but
      none are valid under any specific version of Perl. It used to think all
      Perls were OK when this happened.
      Add the alpha_assertions introduced in 5.27.9.
      Handle 5.27.9's change from +script_run to *script_run, and support
      *sr as a synonym.

      Tokenizer method prior() is now fatal. This was documented as
      package-private, but as it WAS documented, I am putting it through a
      deprecation cycle anyway. Six months from now it will be removed.

      added in Perl 5.27.8. It imposes on any matches it contains the
      additional restriction that everything matched has to belong to the
      same Unicode script. This support will be retracted if the
      functionality does not make it into Perl 5.28.

      Salvatore Bonaccorso for letting me know about this problem..
      Further deprecate tokenizer method prior() in favor of
      Add requirements_for_perl(). This is analogous to the
      CPAN::Meta::Requirements method requirements_for_module(), though
      the output is formatted differently. Also put in the actual
      requirements for an un-escaped literal left curly after a constant,
      which was removed in 5.25.1 and reinstated in 5.27.1.
      Add accepts_perl(). This is analogous to
      CPAN::Meta::Requirements->accepts_module(). I decided that
      CPAN::Meta;:Requirements was overkill, but this may turn out to be
      the wrong decision, so I will be careful what I expose.
      Document behavior of perl_version_introduced() and
      perl_version_removed() when a feature is re-introduced after
      removal, or re-removed after re-introduction.

    Support whitespace inside [] if /xx in effect.
      Starting with Perl 5.25.9, a space or tab appearing inside a bracketed
      character class is not significant if /xx is asserted.
    Further deprecate tokenizer method prior()
    Add 'provides' data to ExtUtils::MakeMaker output
    SOME unescaped litaral '{' removed in 5.025001.
      After '.', Unicode classes, and bracketed classes (including extended)
      they are still legal.
    Make /\b{/ an error
      Perl fails to parse the above, because once it sees the '\b{' it wants
      to find one of the extended boundary assertions (like \b{wb}), and
      declares an error when it does not. So we check for this and rebless the
      curly into an unknown token, not a literal.

    Parse bracketed substitution with embedded comment. This is something
      like s{foo}
{baz} which is equivalent to s/foo/baz/. PPI
      gets this wrong, and we're not smart enough to fix up the PPI parse,
      but if given this as text, we now parse it correctly.
    We now recognize postfix dereferences by default, since Perl does
      beginning with 5.24. In other words, default new() argument
      'postderef' to true.
    Unterminated substitutions (i.e. 's//') should no longer cause an
      exception. Instead they parse as an unknown token.

    Allow nesting of \Q with \U, \L, and \F
      The perlop docs say these nest with each other. Playing with Perl
      suggests that \U, \L and \F supersede each other, but thet they as a
      group nest with \Q in either order, so that if you specify \Q and
      one of the \U, \L, \F group you need two s to turn them all back

    Recognize postfix dereference if desired. This is controlled by the

      default is false, but will become true if postfix dereference
      becomes mainstream Perl 5.
    Add explain() and supporting methods main_structure() and
      in_regex_set(). The explain() method returns a brief explanation of
      what the element does.

    Do not end regex set prematurely on finding '])'
      The problem is that '])' can occur within an extended bracketed
      character class if it contains grouping parentheses and the last

    Clear error when lexer identifies unknown token. Those who peruse the
      changes in this release will see that a bunch of refactoring was
      done as part of this.

    Parse white space inside bracketed character classes inside extended
      bracketed character classes (whew!) as literals, except for the
      space character itself and the horizontal tab. This tracks the
      corresponding change in Perl 5.23.4. This will be reverted if the
      corresponding Perl change does not make it into 5.24.0.

    Beginning with version 0.035, PPIx::Regexp was incorrectly reporting
      the sense of modifiers when the same token both asserted and negated
      modifiers (e.g. '(?x-i:...)'). This release should correct the
    Document policy when Perl changes in such a way that the proper parse
      for a regular expression changes. In this case the more modern parse
      is preferred.

      wholly of white space.

    Group types were not being recognized if they contained the delimiter
      character for the regexp (e.g. in qr<(?\<foo)> the look-behind
      assertion was not recognized as such).
    Correct mis-parse of ' s///'. Leading white space is supposed to be
      acceptable, but the leading whitespace token caused
      PPIx::Regexp::Lexer not to recognize the substitution as such.
    Tokenizer was failing when the string to be parsed was so bad it was
      trying to return the whole thing as a single
    PPIx::Regexp::Dumper now displays a message if a structure is missing
      its end delimiter.

    RT 107331 Produce parse error in the presence of trailing cruft.
      Thanks to Klaus Rindfrey for catching this.
      The tokenizer now does a preliminary scan for delimiting brackets
      and modifiers. Anything after the modifiers except for white space
      is now made into a PPIx::Regexp::Token::Unknown, resulting in a
      parse failure being reported. The previous implementation simply
      assumed a valid expression, and in the case of the expression in the
      ticket blithely mismatched the delimiters and returned a parse
      without failures, but which was manifestly bogus.
    Tweak documentation in PPIx::Regexp.

    Accept non-ASCII whitespace under /x. The Whitespace object can be
      multiple characters; the perl_version_introduced() becomes
      '5.021001' if any of them is a code point above 127.
    The perl_version_removed() method now returns '5.021001' when called
      on a PPIx::Regexp object produced by parsing '?foo?' (match once
      without explicit 'm'). The object produced by parsing 'm?foo?' still
      returns the minimum Perl version.

    Do not parse unadorned parentheses as capture groups when /n is in
      effect. Instead, they are parsed as PPIx::Regexp::Structure. Named
      captures appear to be unaffected by /n.
    Made a verbose dump a little more so. Specifically, dump

      more informatively.

    Recognize nested subscripts in interpolation.
      Thanks to Andy Lester for finding this, which actually manifested in
      Perl-Critic-Policy-Variables-ProhibitUnusedVarsStricter. The problem is
      that the actual heuristics for finding the end of an interpolation are
      undocumented, and I missed this rather-obvious case.

    Handle the boundary assertions introduced in Perl 5.21.9: '{gcb}'
      (grapheme cluster boundary), '{wb}' (word boundary), '{sb}'
      (sentence boundary), and the corresponding '\B{...}' constructions.
      Similar-looking things like '{foo}' are not recognized as
      assertions, and end up being literals.  This is less general than I
      usually make things, but was done against the possibility that
      (e.g.) '{foo}' might be introduced later, requiring
      perl_version_released() to return a different number. Any of these
      retracted prior to Perl 5.22.0 will simply be removed from

    Correctly mark the replacement portion of s///ee as code. Prior to

    Make available the number of times a given modifier is asserted
      (except for the match semantics modifiers which get handled
      differently). See PPIx::Regexp::Token::Modifier->asserted() and
      PPIx::Regexp::Tokenizer->modifier() for details.

   Retract the "Allow non-ASCII white space under /x" change introduced
     in version 0.033. I misread perl5170delta, and implemented early.

   Properly handle multi-character modifiers like /ee. We now handle /eie
     as being the same as /eei. Thanks to Anonymous Monk for finding
   Properly handle \g and \k back references that do not correspond to an
     actual capture group. They are now reblessed into the unknown token,
     and counted as errors. Thanks to Anonymous Monk for finding this.
   Add method error() to PPIx::Regexp::Element. This should return an
     error message when the element is in error -- normally when it has
     been blessed into the unknown token or structure.
   Add method modifier_asserted() to PPIx::Regexp::Element. This walks
     the parse tree backward to determine if the given modifier is in
     effect for the element.

  Reinstate author test xt/author/manifest.t, which was clobbered

  Correct address of FSF in the version of the GPL distributed in
    LICENSES/Copying. Thanks to Petr Pisar for picking this up.

  Correct various documentation errors.
  The default-modifier functionality is no longer considered

  Don't initialize effective modifiers with '^', since that wrongly
    asserts that /d has been seen somewhere along the line.
  Implement negation of match-semantic modifiers (e.g. 'no re /u;') by
    setting the relevant datum to undef.
    WITHOUT NOTICE until the next production release.

  Support for default modifiers. This includes:
    * default_modifiers argument to new() in PPIx::Regexp,
      PPIx::Regexp::Tokenizer, and PPIx::Regexp::Dumper
    * Public method modifier_asserted() on PPIx::Regexp, to return
      whether a given modifier is actually in effect. The results of the
      modifier() method are unchanged.
  Require Test::More 0.88 for installation. Eliminate all the 'eval
    { require ... }' logic in favor of 'use Test::More 0.88'.
  Have Makefile.PL make use of {BUILD_REQUIRES} if it is available.
  Fix PPIx::Regexp::Token::Whitespace->can_be_quantified() to return

  Modified tokenizer to correctly handle a back slash used as a
    delimiter. I believe.
  PPIx::Regexp::Dumper now dumps the results of ppi() if that method is
    present and -verbose is asserted.

    \N{U+xxxx} is now 5.008 (was 5.006).
  The \C is now parsed as a PPIx::Regexp::Token::CharClass::Simple. It

  Understand the /aa modifier, introduced with 5.13.10.
  Report perl_version_introduced() of 5.013010 for the new semantic
    modifiers when modifying the entire expression.
  Correct handling of interpolations like ${^foo} and $#{foo}.
  Override ppi() in PPIx::Regexp::Token::Interpolation to provide the
    proper PPI when variable names are bracketed.
  Properly parse bracketed variable names (I hope!), which may not be
  Take account of possible '$' or '@' casts before a symbol in an
    interpolation (e.g. $$foo{bar}, which is equivalent to $foo->{bar}).
  Add the /a modifier to PPI::Regexp::Token::Modifiers, legal only in
    the (?:...) construction. This was introduced in Perl 5.13.9.
  When parsing an interpolation from a replacement string (rather than a
    regular expression), take subscripts at face value rather than
    trying to disambiguate them from quantifiers and character classes,
    which they can't be in this context.

  * whitespace tweak in the PPIx::Regexp::Dumper test output for the failures test
  * replace the PPI logic in PPIx::Regexp::Token::Code with a call to $tokenizer->find_matching_delimiter(): this is actually the way Perl works, as a look at toke.c and regcomp.c makes clear
