But there _is_ an ordering problem, in that the days wrap around.
Do we want a CircularEnum, then? Ordering would be defined only up to the starting value, which you would be required to specify when doing anything where it mattered. class Day(CircularEnum): sunday = 0 monday = 1 ... saturday = 6 list(Day.startingat(Day.tuesday)) --> [Day.tuesday, Day,wednesday, Day.thursday, Day.friday, Day.saturday, Day.sunday, Day.monday] Modular arithmetic would apply, so Day.saturday + 3 --> Day.tuesday That would be the replacement for Day(3), which would be disallowed. -- Greg _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
