R. David Murray added the comment: 'counter' in the docstrings is in lower case, so that says nothing dispositive. However, __add__ does an ininstance check, so it is hard to see why __iadd__ does not.
Personally I'd drop the isinstance checks and let the errors bubble up as they may. Why should subtract explicitly support other data types, but not __sub__/__isub__? But Raymond's opinion should hold the most weight here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22766> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
