CCALL_VARARGS: cc_func(PyObject *self, PyObject *args)
If we add a new calling convention, I would prefer to reuse the
FASTCALL calling convention to pass arguments: pass a PyObject **args
array with a size (Py_ssize_t nargs) rather than requiring to create a
temporary tuple object to pass positional arguments.

> Let me present PEP 579 and PEP 580.
> PEP 579 is an informational meta-PEP, listing some of the issues with
> functions/methods implemented in C. The idea is to create several PEPs each
> fix some part of the issues mentioned in PEP 579.
> PEP 580 is a standards track PEP to introduce a new "C call" protocol, which
> is an important part of PEP 579. In the reference implementation (which is
> work in progress), this protocol will be used by built-in functions and
> methods. However, it should be used by more classes in the future.
