Subject: [PATCH] Adjust require exception to perl 5.37.8 wording
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With perl 5.38.0 t/memmory test fails on Regexp objects:

    not ok 9 - regex fails the same as require
    #   Failed test 'regex fails the same as require'
    #   at t/memory.t line 99.
    #          got: 'Can't locate object method "INC" via package "Regexp"'
    #     expected: 'Can't locate object method "INC", nor "INCDIR" nor string overload via package "Regexp" in object hook in @INC'
    not ok 10 - class without INC fails the same as require
    #   Failed test 'class without INC fails the same as require'
    #   at t/memory.t line 99.
    #          got: 'Can't locate object method "INC" via package "NonHook"'
    #     expected: 'Can't locate object method "INC", nor "INCDIR" nor string overload via package "NonHook" in object hook in @INC'

This is probably caused by this perl commit which also changed the exception
text:

	pp_ctl.c - Check if refs have overloads in @INC

	If an object in @INC doesnt have a hook method, and it isnt a CODE ref
	then check if it has string overloading, if it does not then die with a
	helpful message, otherwise call the overload

	This uses the nice new amagic_find() function.

This patch adjustes Module::Reader::_open_ref() to emit a similar
exception text. Though it does implement the missing features like
handling INCDIR method or string overloading.

With the new perl it's impossible to get the same exception text in
a different way than by calling "require" function. Therefore
in the long term, I recommend stop insisting on error-to-error parity
and relaxing the tests instead.
