[capi-sig] Re: PyObject_CallOneArg(), ...TwoArgs()

I don't think that it's a good idea. It would require too many functions for all combinations. Like passing an argument as keyword, handling methods, etc. Why only 2? Why not up to 5? :-)

By that argument, we shouldn't have added PyObject_CallNoArgs() either. I think that supporting OneArgs and TwoArgs is a reasonable compromise.

And yes, I also want to do the same thing for methods (PyObject_CallMethodObjNoArgs, ...).

If you want efficient function calls, use Cython which should use the most efficient available API ;-)

I'm talking about code internal to CPython, where using Cython is unfortunately not an option.
