[issue38001] Unexpected behaviour of 'is' operator

Steven D'Aprano added the comment: Further to Karthikeyan Singaravelan comment, the behaviour you see is absolutely correct. The operator isn't behaving differently, it is reporting precisely the truth. The ``is`` operator tests for object identity, not equality. Python makes no promises

Paul Ganssle added the comment: Sorry for the late response after a patch, but I'm actually -1 on this patch. I don't think it buys us very much in terms of the API considering it only has 3 parameters, and it adds some complexity to the code (in addition to the performance issue).
