By using an OrderedDict, names are ordered by first definition point,
rather than location of the used definition.

For example, the definition order of the following will be "x, y", even
though the definitions actually bound to the name are in order "y, x".
        class C:
            x = 0
            def y(self): return 'y'
            def x(self): return 'x'

Is that okay?
