That can't possibly be true. I refuse to believe it.
I mean, I may understand keeping the strange array-is-a-hash thingy, but changing function names is easy.
( used in the dictionary sense, not in the able-ist sense)
I'm more inclined to believe Rasmus is trolling here. Sure, he used strlen, but it's too hard to believe functions were named with this in mind.
So yeah, it's true :).
