When I designed the FASTCALL calling convention, I experimented a new tp_fastcall slot to PyTypeObject to optimize __call__() method: bpo-29259.

Results on the pyperformance benchmark suite were not really convincing and I had technical issues (decide if tp_call or tp_fastcall should be called, handle ABI compatibility and backward compatibility, etc.). I decided to give up on this idea.

I'm happy to see that PEP 590 managed to find its way into Python internals and actually make Python faster ;-)
