Please check out the guile-lightning module from CVS.  It contains the
start for Lightning support in Guile.  You can play arround with the
JIT assembler, but a lot details are missing to really integrate it
into the Guile run-time.

This is actually not at all in competition to a VM based design, since
Lightning is not really portable to every platform we want Guile to
run on.  It is more like an additional performance boost for the most
popular platforms.  Both will need a more or less sophisticated,
traditional Scheme compiler on top of them.  This is an area where the
two approaches can share a lot of effort.

[ It can be argued that things like these is not really what Guile
  needs most right now, that this is premature optimization, etc.
  Well, yes.  But I think better performance will allow us to write
  more things in Scheme, which should speed up development
  considerably.
