I don't see why. I made my PEP with the assumption that the METH_FASTCALL calling convention won't change. As far as I know, nobody advocated for changing it. But even if we decide to change METH_FASTCALL, I could trivially adapt my PEP.

That's why I suggest discussing METHFASTCALL first.

I certainly agree that it's a good idea to discuss METH_FASTCALL, but I still don't see why that should block the discussion of PEP 576/580.

I can understand that you want to wait to implement PEP 576/580 as long as METH_FASTCALL isn't public. But we should not wait to discuss those PEPs.

Jeroen.
