[Python-ideas] Re: Fwd: [Python-Dev] Re: Semi-proposal: Tagged None

I think this is a really good and interesting idea. I do have one question - how would you envision this interacting with the sentinel values from PEP 661 (https://www.python.org/dev/peps/pep-0661/) ? Could 'Tagged None' and sentinel values be the same thing? Thanks, Doug
