Inheritance
"PPIx::Regexp::Token::Delimiter" is a PPIx::Regexp::Token::Structure.
"PPIx::Regexp::Token::Delimiter" has no descendants.
Overview
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".
