A better solution would be to allow only a subset of metacharacters, escaping everything else. This would requre much more effort, but would be safer. Perhaps there is a module that does something like this? If not, there should be.
I'm looking at the Regex:: modules but havn't seen anything yet (search for Regex:: on search.cpan.org and click on any link in the results, mine go now where???) , also perldoc perlre has some things about this but for now I think it'll do me :)
When I finish writing Regexp::Parser,
That sounds interesting. I'm looking forward to hear more about that one. (Already dreaming up uses...)
that seems like a good idea... the ability to parse a regex and strip out (or auto-quote) a specific set of metacharacters.
Yeah, I breifly though of that. Sounds like your module above would make it trivial. FWIW, two interfaces that came to my mind were 1) an enhanced version of quotemeta() and/or 2) a lexical pragma to override qr//.
