A point about the regexes that Regexp::Common doesn't supply

[TheDamian]

Regexp::Common was originally conceived as a framework; one that would allow the Perl community to share and reuse commonly needed (and frequently poorly implemented) regular expressions.

And, indeed, it was been successful in that sense. My original version of the module had very few regexes. Others (principally Abigail-II) have contributed most of the current set it offers.

But because Regexp::Common is contribution-driven, it's entirely possible the module doesn't have the regex you need. Or that you could improve on one of the regexes it does offer (e.g. $RE{profanity}).

In that case, I would strongly encourage you not just to roll your own, but to integrate it with Regexp::Common (I tried to make that trivial to do). Then send Abigail-II the code, so that everyone can benefit.
