for, map, and grep: these three constructs localize $_. But in fact, map and grep are more vulnerable than foreach, because they don't give you the choice of using a lexical as your aliased iterator (iterant?). I did mention this in the talk though I guess the emphasis is stronger when you have more than the slides :)
