[issue38500] PEP 523: Add PyInterpreterState_SetEvalFrameFunc() to the public C API (Python 3.8 regression)

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

I'm not suggesting immediate removal of PEP 532.

I am requesting that you don't add a new function to the C API that will prevent implementation of many meaningful optimizations to CPython.
PEP 532 does not add any API functions.

I understand that you want to fix the regression.
Why not do so by reverting the change that caused it?

Adding a new API function is not fixing a regression.
