'new' has now been deprecated for 3.0, GvR suggested it would be nice to get rid of 'types' as well.

I've removed the 'new' module from py3k and also removed a lot of types from the 'types' module in py3k. It only contains types that aren't easily available through builtins.

Most of those 'hard-to-get-at' types are tied pretty tightly to the interpreter internals, and would fit in with Guido's suggestion of a 'pyvm' module. Such a module would let us clean up the 'sys' namespace a little bit by moving some of the more arcane hackery to another module (like the recursion limit and the threading check interval).

Can we leave 'pyvm' until the next alpha is out? We are already near the schedule for mid to end of November.

The only ones I would suggest putting elsewhere are the module type (exposing it through the imp module instead), and the new dictkeys/values/items types (exposing them through the collections module, as others have suggested).

Several other types are used in the Python core, too. The most remarkable is MethodType (to bind functions to instances) but also FunctionType and CodeType.
