Re: Regex from a string

You're looking for qr//.

Note: what you're trying to can be a really bad thing. The reason is because regexes can theoretically execute arbitrary Perl code using the (?{...}) construct. Now, use re 'eval'; has to be in effect, but if that gets put in by a maintenance programmer later, you're in trouble.

Update: Link to apparently pirated material removed.

My criteria for good software:

Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
