Raymond Hettinger <rhettin...@users.sourceforge.net> added the comment:
The behavior is a PITA. It means that dict subclasses the redefine __setitem__ have unpleasant pickling challenges. The __setitem__ insertions are called before the subclass can initialize. The workaround involves a funky dance using __reduce__. See collections.OrderedDict::__reduce__() for an example. ---------- nosy: +rhettinger priority: low -> normal _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4712> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
