Summary: len() on class broken

Initial Comment:
With the following python input:

class A:
    @classmethod
    def __len__(cls):
        return 12

print '1',A.__len__()
print '2',A().__len__()
print '3',len(A())
print '4',len(A)

The output always breaks for '4' with 'TypeError: len 
of unsized object'

Same result for @staticmethod or normal instance method 
declaration.
