[Python-3000] State of the object system

[Kay Schluehr]

I wonder what is the current state of type/class unification i.e. "new 
style classes"?

The Python 2.5 library reference ( chapter 2.3 ) still states that this 
issue is being "far from complete".
( BTW this signals the user that the object system is quite immature and 
early alpha. Maybe one should
rethink commenting the current state of development all over the public 
docs? )

Since we discuss new features here I would like to listen what people 
think about opening builtin types?
So far Python has a protective policy to not let users add a method to 
e.g. an int or str. Is there a deeper
design issue or is it for pure implementation/optimization reasons?
