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".
