You'll be able to do that soonish. I'm working on a patch to Perl that will allow you to do character class set operations: s/[$start-$end^^$keep]//. That is, if $start = "a", and $end = "z", and $keep = "aeiou", the character class would be everything from "a" to "z" except "a", "e", "i", "o", and "u".
