Ronald Oussoren added the comment: You've got a point there. What about this patch (but then with proper english grammer)?
BTW. Actually fixing this wart would be possible, but at a significant cost: you'd have to change the implementation of LHS += RHS from: tmp = LHS tmp = tmp.__iadd__(RHS) LHS = tmp to: tmp = LHS LHS = tmp tmp = tmp.__iadd__(RHS) LHS = tmp The odd assignment on the second line would detect that the LHS is immutable in 99+% of use cases before updating the RHS. My gut feeling is that an implementation of this would have too high a cost (both in runtime performance and in a more complicated compiler), although it would be interesting to actually see a patch. ---------- keywords: +patch Added file: http://bugs.python.org/file30294/faq-update.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
