My spam filter uses a regular expression with about 100 terms |ed together. Perl get stuck when some strings are evaluated against the regular expression. I broke the re into pieces and it began working again.

These are generally simple strings. I could do something like:

foreach (@string) {
 return 1 if index($s,$_);
}
return 0;

But That must be slower than 
 return $s=~/$match1/io;

[download]
especially because this is done hundreds of times per email.

So what I'm looking for is something like flex to generate a fast RE scanner for BIG re's, without some of the limitations (or power) of perl's builtin re's.

I've poked around at cpan, but noting jumped out at me.
