   Not at all. The magic is in the order of registry keys. Registry is a
dictionary, and Python handles dictionary's keys in a random order:

>>> print {"Author": 1, "Person": 1, "Retired": 1}.keys()
['Person', 'Retired', 'Author']
>>> print {"Employee": 1, "Person": 1, "Retired": 1}.keys()
['Employee', 'Person', 'Retired']

   This cause the internal loop that builds the list of parent classes
to behave differently. This is a bug, of course, and I'm continuing
hunting for it.
