Um, can I be a little confused?  If you are writing code that you know
will be run in 2.2 and later, you write

   isinstance(obj, int)

If you want to support 2.1 and so on, you write 

   isinstance(obj, types.IntType)

What would writing 

   isinstance(obj, types.int)

ever gain you except restricting execution to 2.3+?

I mean, I don't have any real opinion *against* this pep, I just don't
really see why anyone would care...

Cheers,
