\&\f(CW\*(C`PPIx::Regexp::Token::Delimiter\*(C'\fR has no descendants.
.SH "DESCRIPTION"
.IX Header "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.
.SH "METHODS"
.IX Header "METHODS"
This class provides no public methods beyond those provided by its
superclass.
.SS "perl_version_introduced"
.IX Subsection "perl_version_introduced"
Experimentation with weird delimiters shows that they did not actually
work until Perl 5.8.3, so we return \f(CW\*(Aq5.008003\*(Aq\fR for such delimiters.
.SS "perl_version_removed"
.IX Subsection "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 \fIperldeprecation\fR, I take this to
mean characters that match \f(CW\*(C`/\ep{Mark}/\*(C'\fR (i.e. combining diacritical
marks).  But this regular expression does not compile under Perl 5.6.
.PP
So:
.PP
This method returns \f(CW\*(Aq5.029\*(Aq\fR for such delimiters \fBprovided\fR the
requisite regular expression compiles. Otherwise it return \f(CW\*(C`undef\*(C'\fR.
