Well, okay, but that doesn't help the programmer who's trying to write portable code. Some extensions, like vector processing, won't be standardized for a very, very long time. Does that mean the programmer shouldn't be able to write code that will take advantage of vectors when they're around? Does it mean that all such code must be unportable? ---Dan
