Heh, amazingly enough, the compiler subsystem of CMUCL also, by complete
coincidence, happens to be called Python.

I think Lisp compiler techniques can be used for Python, but some
parts of Python semantics are messier to compile.  That's no big
surprise; Lisp semantics evolved over the years directly in response
to the needs of Lisp compilers.  I think Python will probably evolve
the same way and I hope PyPy is deployable soon, since that will speed
up compiler development a lot.  I think we should consider a
semi-moratorium til then on new language features that might affect

I don't remember what that was about, but I can guess which guy I must
have been thinking of.  He's still around and used to read this newsgroup
