Have you tested with the new typing.py yet? #30

While Python 3.6 is in beta we're changing the way typing.py represents types. I can't make any promises that it'll stay stable until the 4th beta (after all PEP 484 is still provisional) but I figured I should give you a heads up that we're changing things around. You can follow the fun in our repo: https://github.com/python/typing/

As of this afternoon (since I finally got around to installing 3.6), enforce does not work with Python 3.6. Attached is stack trace of import error. I'll start digging deeper in the next few days and see what's changed and where the problems lie.

Thank you. The latest version of Enforce.py now also works with Python version 3.6.0.

By the way, is there a single page changelog for the typing module anywhere? It is quite tedious to catch all the API changes through manual testing.

The commit log on the Python/typing repo should cover it.
