It would be really helpful to see the patch that removes use of the
types module from the standard library. I counted over 100 imports of
the types module in the 2.6 standard library. Some of the fixes are
obvious, like::

    if type(etype) is types.ClassType

which in 3.0 should obviously be::

    if isinstance(etype, type)

But other ones are not as obvious to me::

    bdb.py:        if not isinstance(cmd, types.CodeType):
    bdb.py:        if not isinstance(expr, types.CodeType):
    copy.py:    d[types.CodeType] = _deepcopy_atomic
    idlelib/rpc.py:copy_reg.pickle(types.CodeType, pickle_code, unpickle_code)
    inspect.py:    return isinstance(object, types.CodeType)
    trace.py:        if isinstance(c, types.CodeType):

If someone could actually do the conversion, and show the new way to
write these things, I'd feel much more confident on removing the
module.
