Serhiy Storchaka proposed to use a single C array for positional and
keyword arguments. Keyword arguments are passed as (key, value) pairs.
I just added this function:
PyAPI_FUNC(PyObject *) _PyObject_FastCallKeywords(
PyObject *func,
PyObject **stack,
Py_ssize_t nargs,
Py_ssize_t nkwargs);
The function is not used yet. Serhiy proposed to enhance the functions
to parse arguments to support this format to pass arguments which
would allow to avoid the creation of a temporary dictionary in many
cases.
I proposed to use this format (instead of (PyObject **stack,
Py_ssize_t nargs, PyObject *kwargs)) for a new METH_FASTCALL calling
convention for C functions:
