Aside from constructing two closures in the same context and proving that their __code__ attributes point to the same object, is there any way to distinguish between "code object compilation time" and "def execution time"? I just played around with it, and as far as I can tell, code objects are completely read-only. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
