Python won't be reengineered.  If the Perl VM happens to be able to
retargetable for Python, maybe some synergy might happen (like
reusable C extensions).  But I don't see Python making any compromises
in its semantic model, and the new VM would only be used for something
like Python 3.0 (or more likely 4.0) if it really offers significant
advantages.  Dan's recent contributions make me a lot less optimistic.
Don't ask me to explain -- I don't have the time, sorry.  The other
participants in the thread are doing a good job.
