All that's going into 3.5 is the typing.py module, which will also be
distributed on PyPI.  The actual type checking is being left to
third-party tools like MyPy (which was the basis for the typing.py
module).

I'm not sure if there is any plan to ever include an actual type
checker with the base Python distribution.
