Hmmm.. I'm inclined to doubt that this is true for all cases. In principle, I'd agree, but saying that anything expecting a return list is too simple an assumtion.

I'm quite sure (although I'm too lazy now, to come up with some proof) that I'd find a map with a discarded return list that does something faster than an equivalent for/foreach.

BTW, has someone thought that a smart while() might be fastest anyway?
