I'm definitely going to cover tr/// in the "optimization" section, showing how to change something as silly-looking as s/[aeiou]//gi to the far more competant tr/aeiouAEIOU//d.

Don't fear; I'll be discussing functions that are oft or best employed with regexes, especially split() and its magical first argument.
