Cool. I appreciate the clarification. I had always taken an empty dictionary as a dictionary object without data, and a NIL as not an object, and the two were different. This helps my PDU checking.
And I also found the update I missed which added is_pdu(), which simplifies some of my checking. So, even better!

Yes, an empty dict is NIL, so that is (confusingly) valid.

I was just wondering if pmt.PMT_NIL is considered a valid dictionary object, as opposed to, my_dict = pmt.make_dict() self.assertTrue(pmt.is_dict(my_dict)) Just trying to get a better understanding and couldn’t find an answer.
