Psyco, the Python Specializing Compiler

The psyco.compact documentation states the following:

Weak references to instances are not allowed. (Please write me if you would
like me to remove this limitation.)

I'm writing to request you remove that restriction. :-)

I have a home-brewed cache that I use to store data grabbed from a database
backend. The cache uses (among other things) a weakref dictionary so that
objects are not reloaded from the database if anything else in Python is
still it. I'd like to use psyco.compact so each object uses as little
memory as possible.
