While I agree with the above assertions that it's totally silly to
compare something with True, throwing a warning isn't desirable. If
you're going to write something to handle this, the tp_compare method
on the bool object should return
PyObject_IsTrue(a) == self->ob_ival ? Py_True : Py_False
Of course about a week after that's done somebody is going to point
out that "3 is True" is false (as it should be).
