Thanks for your reply. It's been a while since I've used psyco, and it seems either some functions have been added, or I've never needed the other ones. :-)
For the record, it looks like psyco.bind (f) f2 = psyco.unproxy(f) would leave me with an optimized f and a function f2 which is the unoptimized version of f. In any case, it looks like I need to RTFM a little more. Thanks Paul -- http://mail.python.org/mailman/listinfo/python-list
