Guido van Rossum added the comment: I find it extremely suspicious that if you pickle the keys of a large object it also pickles that object. These are views, not copied data, for a reason. I also take back that this is okay for concrete dict.
As for your reason (http://bugs.python.org/issue23401#msg267317), that doesn't explain the use case for pickling keys views. If you forbade pickling them would any user code break? I seriously doubt it. Who on earth would want to pickle a keys view on an OrderedDict? It doesn't contain any information other than the underlying object. These views exist as alternate APIs to dicts, not as objects by themselves. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23401> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
