Mea culpa: Here super is _not_ a good idea, and I had tried that
and recoded, but cut and pasted the wrong code. I just noticed
that I had done so this morning.
class Initialized(ClassBase):
@classmethod
def _init_class(class_):
class_.a, class_.b = 1, 2
ClassBase._init_class()
print Initialized.a, Initialized.b
Much better. There is probably a way to get to the MRO, but for now,
this should do.
