[issue46323] Use _PyObject_Vectorcall in Modules/_ctypes/callbacks.c

STINNER Victor added the comment: A benchmark on calling C functions using ctypes sounds better than a benchmark calling Python functions. For Python functions, Python objects are converted to C types, and then C types are convered back to Python objects, the Python result is converted to a

[issue46640] Python can now use the C99 NAN constant or __builtin_nan()

STINNER Victor added the comment: > Adding new C99 features needs a change in PEP 7 > (https://www.python.org/dev/peps/pep-0007/#c-dialect) IMO this PEP is outdated for a long time. C99 standard is wide. Do we have to explicitly list every single function, macro or constant used by Python?
