Documentation is a very good idea.
Maybe, even raise an error when comparing values.

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:
- 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?
