A discussion of that, and why you think the new position outweighs the original decision, should be included in the RFC. (At the moment I'm undecided; yeah it's an easy enough utility to add, but the UTF-8 issue is real, and one could easily argue that it's stripos() that's wrong, because it's misleading as it only works on ASCII.) The ideal answer would be Derick's built-in String object RFC, which I don't think has been touched in a while, sadly... --Larry Garfield
