That's a lot of overhead for e.g. 'i -= 1'.
Hmm. I agree this isn't ideal, and I now see the attraction of two's complement. Thanks. It would be interesting to see timings from such an approach. Maybe one could just implement the basic operations (+, -, *, /) to get an idea of whether it's worth considering more seriously. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1087418> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
