PyObject_CallObject (or PyObject_CallFunction) are what you need,
see 6.1 in the API reference manual.  But of course you need the
object for the class, just as you need the PyObject* for any other
Python object to do something with it!  PyRun_String (see part 2
in the reference manual) may be a quick & dirty way to get it, but
you still need the object pointers for the globals & locals dicts.
