Is the gain from this kind of micro-optimization really worth the cost of replacing obviously correct code with code whose correctness needs several minutes of thought?
The original code isn't all that obviously correct to me either. I would need convincing that the arithmetic being used to check for overflow can't itself suffer from overflow. At least that much is obvious from the new version. -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
