Dear Python developers,

I would like to request a review of PEP 575, which is about changing the classes used for built-in functions and Python functions and methods. The text of the PEP can be found at

The motivation of PEP 575 is to allow introspection of built-in functions and to allow functions implemented in Python to be re-implemented in C. These are excellent goals.

That summary misses the 3rd goal, which is the one that answers your other questions: to allow 3rd party extension modules access to the hot paths in CPython that are currently restricted to true built-in and Python native functions (without making those hot paths measurably slower).

Cheers, Nick.
