Thanks :b, I'd forgotten I'd written that, (they are still some of the 
stranger code I worked on).


That aside, I also am looking for a set implementation. I'm going to 
need light weight (struct not class, can't hammer the heap), fast (O[1] 
for most ops), and I'll need add, remove and contains check. really 
void[T] AA's would do everything I need, if the performance is good 
enough. Oh and it must allow closed source use.
