What exactly are you requesting though? - Split on the "edge" lowercase to uppercase? - Split on uppercase but keep the uppercase element?
Thinking about this more: Do you *actually* have two different predicates, or are they mutually exclusive? EG: predicate "isUpper", and split on a false->true?
Either way, it shouldn't be too hard to implement. Base it off "splitter!pred", which is actually quite trivial. AFAIK, your requirements could even make it simpler, since you don't need to "skip" the splitter element (which, for strings, can actually be tricky business...).
You'd just have to use 2 calls to find though, for "both your predicates" or for "not predicate then predicate".
