This isn't accurate. The OrderedClass example uses an OrderedDict to
remember the method creation order:
def __new__(cls, name, bases, classdict):
result = type.__new__(cls, name, bases, dict(classdict))
result.members = tuple(classdict)
return result
The instantiated objects __dict__ will still be a regularly
dictionary, while the assignment order is stored in the class
attribute .members.
