I didn't meant comparing tp_fastcall and your PEP.

I just meant we need to compare complexity and benefit (performance), and we need reference implementation for comparing.

I has a quick look at that patch and it's really orthogonal to what I'm proposing. I'm proposing to use the slot instead of existing fastcall optimizations. Victor's patch was about adding fastcall support to classes that didn't support it before.
