Objects of classic builtin types don't even have the __class__ attribute.

>>> type(A)
<type 'classobj'>
>>> A.__class__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: class A has no attribute '__class__'
>>> type(C)
<type 'type'>
>>> C.__class__
<type 'type'>
