Ronald Oussoren added the comment: David: your update to the FAQ looks ok to me.
I don't like updating the __setitem__ of tuple to allow setting an identical value (that is 'a[0] = a[0]'), it is a bit too magic to my taste and hides the real problem. I'd slightly prefer my idea: update the code generated for += to try performing the assignment before calling __iadd__. I hadn't looked at the AST compiler before, but at first glance implementing my idea seems easier than I had expected and I'm working on an experimental patch. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17973> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
