ref objects behave differently: they inherit their referent's hash value when alive, and remember it. proxy objects could be made to behave the same way. > The hash support for ref objects is definitely a very special case, > only intended to support WeakKeyDictionary I've relied several times on the hashability of ref objects, in third-party code. (OTOH, I never use weakref proxies) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24067> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
