If we put technical considerations aside, maybe we should just ask to ourselves what behavior do we expect when doing equality tests between ordered dictionaries. As a reminder:
xy = OrderedDict([('x', None), ('y', None)]) yx = OrderedDict([('y', None), ('x', None)]) xy == yx
False
xy.items() == yx.items()
True
xy.keys() == yx.keys()
True
xy.values() == yx.values()
False
So, it appears that: 1. equality tests between odict_values use objects identity and not equality, 2. equality tests between odict_keys do not respect order.
If it is not technically possible to change the current implementation, maybe all we can do is just add a warning about current behavior in the documentation?
