Thanks Adam, this looks pretty good!

To everyone else: this is a fairly sizeable amount of C++ code which adds a
little bit to our binary size (probably ~2%) and build time (probably ~8%),
but the performance gains, extra features and better maintained code are
probably worth it. I'm still reviewing and would like to get build time
impact a little lower still; if anyone else is interested please weigh in
though.

Cheers,
Ralf
