Experimentation with weird delimiters shows that they did not actually work until Perl 5.8.3, so we return '5.008003' for such delimiters.
'5.008003'
Perl 5.29.0 made fatal the use of non-standalone graphemes as string 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.
/\p{Mark}/
So:
This method returns '5.029' for such delimiters provided the requisite regular expression compiles. Otherwise it return undef.
'5.029'
undef
