Okay, I know when I'm beaten :-) Documentation will no longer make reference to "honouring the context", as currently stated, and specific example shown will be dropped. Patch to follow. Changing the actual implementation of sum will follow later. If Oscar is willing, I'd like to discuss some of his ideas off-list, but that may take some time. What else is needed before I can ask for a decision on the PEP? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18606> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
