1. don't do that. search on perlmonks and you'll find a long discussion with benchmarks. that takes quite a bit longer and isn't much more typing than separating them out. though, i don't know whether putting the regex in an array and doing $string ~~ @reg might be as slow as that. 2. don't top post - i cut out the rest of the conversation because i had no other way to respond inline. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
