could have it both ways--have both AUTO_OP new(p, ic) and AUTO_OP
new(p, sc). FWIW, though, I don't think the class numbers are actually

In preparation of more realistic regex opcodes (which will all be
prefixed with rx_), I've committed some changes to allow underscores in

through 'frame' probably didn't help much.
I can provide source for everything on request, including a new core.ops
and some supporting files, the test assembly file, and the benchmark
