Danger will robinson!

Never use $1 unless it's in the context of a conditional based on the success of the match. Otherwise, you get the previous success $1, and that's gonna bring you to tears while you're trying to debug it.

Most people will tell you to learn from your mistakes, but I always think it's 100% better if you can learn from someone else's mistakes. This is actually one of the great reasons I visit Perlmonks -- the cooperative learning can't be beat! p.s. no offense intended to raflach: I might have made the same mistake.	[reply]
