To avoid warning above produced by using
-Wcast-function-type we;
+ ensure PyCFunctions of type METH_NOARGS defined dummy arg
+ ensure PyCFunctions of type METH_KEYWORDS use PY_DISCARD_FUNC_SIG
macro
+ ensure PyCFunctions of type METH_KEYWORDS really actually use the
problematic kargs param, if not remove it
