and *args*.
The *self* argument is only used when the C function implements a built-in
method, not a function. In the example, *self* will always be a *NULL* pointer,
since we are defining a function, not a method. (This is done so that the
interpreter doesn't have to understand two different types of C functions.)
The *self* argument points to the module object for module-level functions;
for a method it would point to the object instance.
The *args* argument will be a pointer to a Python tuple object containing the
arguments. Each item of the tuple corresponds to an argument in the call's
