  It precompiles it.  Not to full-on machine code (at least, by default), but
to a bytecode language which should be amply fast for these purposes.

  This is a great thing to do in LPC.  There are significant problems with
writing a C implementation and building it into the driver.  LPC will be far
more convenient and upgradable, and the speed and size issues should be very
small.

  Enough people have asked about this on the mailing list over the years that
I'm sure somebody has done something very much like it.  Sadly, none of them
have released their code.
