NAME

       PPIx::Regexp::Token::Delimiter - Represent the delimiters of the regular expression

SYNOPSIS

        use PPIx::Regexp::Dumper;
        PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
            ->print();

INHERITANCE

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

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

DESCRIPTION

       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.

METHODS

       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".
