It's not so much a micro-optimization than the fact that pushing a block on the stack is very cheap. IIRC, what is expensive is: - creating the exception object with the associated traceback - matching the exception in the "exception SomeException" clause I don't have numbers, though :-) Regards Antoine. _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
