Python looks up special methods on the class, not the instance (see
http://docs.python.org/reference/datamodel.html#special-method-lookup-for-n=
ew-style-classes).

It seems like you ought to be able to delegate the special attribute
access from the class to the instance somehow, but I couldn't figure
out how to do it in a few minutes of fiddling at the interpreter.
