Patch with unit test attached for MutableSet's: x ^= x x -= x I was wrong about |= and &= having a problem. Since they don't mutate the set, they don't raise an exception (they only .add items that are already in the set). I added tests for them but left the implementation alone. ---------- keywords: +needs review, patch stage: unit test needed -> patch review Added file: http://bugs.python.org/file17432/set-isub.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8750> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
