Thanks for the suggestion. I do prefer to avoid having to use $1 for just trimming some characters. My regex worked for what I needed to do and since I'm only running this on 15 to 20 strings I wasn't worried about optimization. I find that other people's regexes are usually hard to read at first. I'm curious why you say mine is inefficient. Did you do some benchmarking?

In your regex ( $module =~ s/\-[^-]*$//; ) the backslash isn't needed for a '-'.

Rule of thumb: Try to make all your patterns start with a character and not a wildcard.

I was just reviewing the regex documentation and I didn't see that one listed. There are a lot of examples however where they don't start with a character. Are you including character classes as characters?
