It's not a cheat, it's an accident you have no protection against.

Consider:

class Secret(NotSoSecret):
     # pass

Looks like you must know every one of the base classes of the NotSoSecret,
whether there is some base class named Secret? And, if so, you must also
know these classes _implementation_, every one of their attributes,
variables and methods, to avoid accidental overriding?

For me, it's not what inheritance is about. This accident should be rare,
but possible.
