If you don't already know about it, the full metacircular evaluator I
wrote for SBCL is in SBCL's evaluator-again-branch.  It hasn't been
touched for about five months, unfortunately.

The evaluator itself is done.  Missing is integration into things like
the debugger and TRACE.  It is also mostly portable.

Most of the guts are in:
