perl v5.36.0                                       2023-03-05                PPIx::Regexp::Token::Delimiter(3pm)

       This token represents the delimiters of the regular expression. Since the tokenizer has to figure out
       where these are anyway, this class is used to give the lexer a hint about what is going on.

       "PPIx::Regexp::Token::Delimiter" is a PPIx::Regexp::Token::Structure.

       "PPIx::Regexp::Token::Delimiter" has no descendants.

       This class provides no public methods beyond those provided by its superclass.

   perl_version_introduced
       Experimentation with weird delimiters shows that they did not actually work until Perl 5.8.3, so we
       return '5.008003' for such delimiters.

   perl_version_removed
       Perl 5.29.0 made fatal the use of non-standalone graphemes as regular expression delimiters. Because non-
       characters and permanently unassigned code points are still allowed per perldeprecation, I take this to
       mean characters that match "/\p{Mark}/" (i.e. combining diacritical marks).  But this regular expression
       does not compile under Perl 5.6.

       So:

       This method returns '5.029' for such delimiters provided the requisite regular expression compiles.
       Otherwise it return "undef".
