Redirecting discussion from python-checkins to python-dev.
'new' has now been deprecated for 3.0, GvR suggested it would be nice to
get rid of 'types' as well.

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).
The only ones I would suggest putting elsewhere are the module type
(exposing it through the imp module instead), and the new
dict_keys/_values/_items types (exposing them through the collections
module, as others have suggested).
Cheers,
Nick.
