There are two different things here:
The first is documenting METH_FASTCALL such that everybody can create
built-in functions using the METH_FASTCALL signature. I think that the
API for METH_FASTCALL (without or with METH_KEYWORDS) is fine, so I
support making it public. This is really just a documentation issue, so
I see no reason why it couldn't be added to 3.7.0 if we're fast.
The API for calling functions using the FASTCALL convention is more of a
mess though. There are functions taking keyword arguments as dict and
functions taking them as tuple. As I mentioned in PEP 580, I'd like to
merge these and simply allow either a dict or a tuple. Since this would
require an API change, this won't be for 3.7.0.
