You should realize that the name 'Point' within Python does not refer to a
type, but a function (type 'builtin_function_or_method').  You can easily
(or maybe not so easily) modify the extension module so that 'Point' is
instead an object that acts like a function but also has additional
properties, such as the ability to hold attributes.  This is totally
different from modifying the actual type 'Point'.
