What do you know about the contents of 'argc' and 'argv'?  If it's
impossible with Py_Main, can you use one of the other entry points?

If you've never manipulated PyObject* objects in C, they can be
hairy.  Even if you know 'a' is a sequence, its contents are still all
PyObject*s, which you can access via PyList_... and PySequence_
functions.
