No.  He just made clear today that he values stability over 
non-functional consistency changes -- especially now that 3.0 is out.

As I remember, int, str, etc, once *were* functions (or at best types) 
rather than callable class objects.  Before 2.2, built-in types and 
user-defined classes were separate categories of entities.
