The Python C API has many functions to call a function or a method: https://docs.python.org/dev/c-api/call.html

The PyEval variants were deprecated in Python 3.9. I propose to now remove them:

• PyEval_CallObject()
• PyEval_CallObjectWithKeywords()
• PyEval_CallFunction()
• PyEval_CallMethod()

There are replacement functions like PyObject_Call() and PyObject_CallFunction() which exist since Python 3.0 at least and so is backward compatible.

   Replacing PyEval_CallObject(func, args) with PyObject_Call(args) does crash if args is NULL. Python 3.9 added PyObject_CallNoArgs() for this purpose: https://docs.python.org/dev/c-api/call.html#c.PyObject_CallNoArgs

   The PyEval_Call*() functions are not documented and not tested.
