[Python-ideas] OrderedDict for kwargs and class statement namespace

Just wanted to put out some feelers for the feasibility of these two features: * have the **kwargs param be an OrderedDict rather than a dict * have class definitions happen relative to an OrderedDict by default rather than a dict, and still overridable by a metaclass's __prepare__(). Both of these will need OrderedDict in C, which is getting close (issue #16991). -eric
