I don't know why I thought name mangling only happened at the module
level... But note that even here it's still usable, and that the user
has broken the rule of 'leading underscore == leave it alone'.

>>> class Test:
...     def __private(self): pass
...
>>> dir(Test)
['_Test__private', '__doc__', '__module__']
>>> dir(Test)
['_Test__private', '__doc__', '__module__']
>>> Test._Test__private
<unbound method Test.__private>
>>>
