I'm sorry, but I hadn't realized which compact ordered dict is
not ordered for split table.
>>> class A:
>>> a = A()
>>> b = A()
>>> a.a = 1
>>> a.b = 2
>>> b.b = 3
>>> b.a = 4
dict_items([('a', 1), ('b', 2)])
dict_items([('a', 4), ('b', 3)])
This doesn't affects to **kwargs and class namespace.
But if we change the language spec to dict preserves insertion order,
this should be addressed.
