The C++ standard library "general regex engine" is crap (at speed), so there's no competition on that front at least...

I know. I'm not really looking to compare it with C++'s standard library regex engine. (Although if someone wanted to do that work, I would welcome it into the benchmark.)

There are other engines written in C++ (in part or in whole) in rebar. And it is useful to compare it with engines not written in C++ too.
