Have you tried for Cython (aka extension type) subclasses of
SageObject, like e.g. Integer?
sage: x = 1
sage: x.__class__
<type 'sage.rings.integer.Integer'>
sage: x.__class__.foo = lambda self: 1

Traceback (most recent call last):
...
TypeError: can't set attributes of built-in/extension type
'sage.rings.integer.Integer'
Cheers,
Nicolas
