RSN or when Dan's string stuff is merged. > How about for creating and manipulating character classes? There is an implementation of bit sets in imcc/sets.c. The old rx code has some bitmap stuff in src/rx.c. But that's broken WRT memory leaks. It uses a bitmap for chars < 256 and a linear string for anything bigger - suboptimal. So it's probably best to to create a BitSet PMC. That could use a bitset for the "normal" range of the charset and an additional hash for other values, which is searched only if it's there. > Apologies in advance if I've simply overlooked something.
