[New-bugs-announce] [issue43244] Move PyArena C API to the internal C API

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Include/cpython/pyarena.h declares 4 functions which are implemented in Python/pyarena.c. The header file exists to access these functions from the compiler. IMO there was no intent to expose these functions to the public Python C API.

Moreover, the PEP 384 explicitly excludes this API from the stable ABI (from the limited C API).

I propose to move these functions to the internal C API.

Since these functions are no even documented, I don't think that a deprecation period is needed.

Note: The PR 24550 moved Include/pyarena.h to Include/cpython/pyarena.h.
