The signature of PyEval_EvalCodeEx now gets a "PyObject *kwdefs" parameter but the doc doesn't mention it.

It looks like a basic description of kwdefs was added as part of this commit: https://github.com/python/cpython/commit/7811a5d1c93f2aa0b357444eeb3f1ddc242ac57a

"keywords and defaults," however, the kwdefs argument was never added to the prototype.

I've attached a patch which adds the argument to the prototype and clarifies the language a little bit.

> "keywords and defaults," however, the kwdefs argument was never added to the prototype.

I don't think this is about the missing "kwdefs". I think "arrays of arguments, keywords and defaults" is a whole part describing "PyObject **args, int argcount, PyObject **kws, int kwcount, PyObject **defs, int defcount". "kwdefs" is a dict containing the default values of keyword-only parameters in Py3? I am not sure.

You're completely right, the kwdefs is referring to default arguments for keyword-only-arguments from this PEP: https://www.python.org/dev/peps/pep-3102/

Where as that line is probably referring to "defs", the defaults for normal parameters.

I'll upload an amended patch.

Updated patch for review comments

Updated patch to include a cross reference to keyword-only arguments since I think not everyone will know about this rather new feature.
