 >>> class Foo(property):
...  __slots__=[]
...
 >>> x=Foo()
 >>> x.__doc__ = "asdf"
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'Foo' object attribute '__doc__' is read-only

You can't add arbitrary attributes to instances, since some instances  
don't have the slot to put them in.

Is that an equivalent demonstration to that which boost runs into?  
(except, it's using a C type not a python type).
