[issue27576] An unexpected difference between dict and OrderedDict

[Raymond Hettinger]

Raymond Hettinger added the comment:

This does need to be fixed.  

FWIW, here is the relevant docstring from MutableMapping:
        ''' D.update([E, ]**F) -> None.  Update D from mapping/iterable E and F.
            If E present and has a .keys() method, does:     for k in E: D[k] = E[k]
            If E present and lacks .keys() method, does:     for (k, v) in E: D[k] = v
            In either case, this is followed by: for k, v in F.items(): D[k] = v
        '''
