Thanks. As expected for calls to C function for both PEPs and master
perform about the same, as they are using almost the same calling
convention under the hood.
As an example of the advantage that a general fast calling convention
gives you, I have implemented the vectorcall versions of list() and range()
https://github.com/markshannon/cpython/compare/vectorcall-minimal...markshannon:vectorcall-examples
Which gives a roughly 30% reduction in time for creating ranges, or
lists from small tuples.

Cheers,
Mark.
