Brett Cannon <br...@python.org> added the comment: There is a difference between methods and overridden operators (slightly) in terms of cognitive understanding. I mean creating a new instance from a timestamp seems like an operation on the object by the object. Addition, though, seems like a creation of a new object by the two objects working together, which suggests contravariance.
Best I can think of. Otherwise ask on python-dev since Guido called the operator overriding expectation. ---------- nosy: +brett.cannon _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2267> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
