Content
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.
