%description
When "looping over hashes," we mean looping over hash keys or hash values.
If you forgot to call 'keys' or 'values' you will accidentally loop over
both.

    foreach my $foo (%hash) {...}        # not ok
    action() for %hash;                  # not ok
    foreach my $foo ( keys %hash ) {...} # ok
    action() for values %hash;           # ok

An effort is made to detect expressions:

    action() for %hash ? keys %hash : ();                             # ok
    action() for %{ $hash{'stuff'} } ? keys %{ $hash{'stuff'} } : (); # ok

(Granted, the second example there doesn't make much sense, but I have
found a variation of it in real code.)
