Like function objects, methods objects support getting arbitrary attributes.
However, since method attributes are actually stored on the underlying function
object (``meth.im_func``), setting method attributes on either bound or unbound
-methods is disallowed. Attempting to set a method attribute results in a
-:exc:`TypeError` being raised. In order to set a method attribute, you need to
-explicitly set it on the underlying function object::
-
- class C:
- def method(self):
- pass
-
- c = C()
- c.method.im_func.whoami = 'my name is c'
+methods is disallowed. Attempting to set an attribute on a method results in
