No, it would have to be written like this:
>>> from types import *
>>> class MyInt(IntType): # add a method
def add1(self): return self.value+1
>>> i = MyInt(10)
>>> i.add1()
11
>>>
Note the value attribute. The IntType.__init__ method is
basicly:
def __init__(self, value):
self.value = value

Yes, the instance attributes. In this scheme all objects are
instances of some class.

Right. My changes on the weekend where quite close to making
