Now you're really pulling my leg. PyObject_RichCompareBool is just:
/* Return -1 if error; 1 if v op w; 0 if not (v op w). */
int
PyObject_RichCompareBool(PyObject *v, PyObject *w, int op)
{
PyObject *res = PyObject_RichCompare(v, w, op);
int ok;
if (res == NULL)
return -1;
ok = PyObject_IsTrue(res);
Py_DECREF(res);
return ok;
}
How can that be more efficient that PyObject_RichCompare?
