I chose to not document FASTCALL on purpose in Python 3.6, I wanted to keep everything private, until we get enough feedback and stabilize the API.

Recently, the FASTCALL API changed: METH_FASTCALL doesn't support keywords anymore. You have to pass METH_FASTCALL|METH_KEYWORDS.

It seems like the API became stable.

I don't know if we should make the API public or not. PyPy would complain as usual that we give them more work to do :-D
