While the psyco-like tricks for specialization should definitely improve the interpreter, there is a second trick (watch for exploding heads here). The big trick is that you can specialize the interpreter for running _its_ input (a Python program), thus giving you a new interpreter that only runs your Python program -- a very specialized interpreter indeed. --Scott David Daniels [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
