Gareth Rees added the comment: > I don't see any reason for proxy objects to be less hashable than ref objects.
The difference is that unlike a ref object, a proxy object is supposed to forward its method calls to the proxied object. So consider what happens if you forward the __hash__ method to the proxied object: the hash will change when the object dies. A proxy object could, of course, not forward the __hash__ method, instead computing its own hash. But I think this would do more harm than good: surely most attempts to store weakref.Proxy objects in sets or dictionaries are going to be mistakes -- the user should have used a WeakKeyDictionary or a WeakSet instead. ---------- _______________________________________ 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
