Not disputing when it happened, more the why...

...the recommended change doesn't work, for obvious reasons:

 >>> MyClass.method.__self__.__class__
Traceback (most recent call last):
   File "<console>", line 1, in <module>
AttributeError: 'function' object has no attribute '__self__'

The loss of the ability to figure out the class from an unbound method 
seems quite an annoying step back from an introspection point of view.

cheers,

Chris
