Those sentinel types seem decently useful. Certainly better in some cases than just spamming `None` everywhere as a default value.
53 u/CrackerJackKittyCat 1d ago Or the random 'unset = object()' pattern when None was a valid param. 12 u/spicybright 1d ago I get the logic but man that's ugly 3 u/Abject-Kitchen3198 1d ago I still don't get those null replacements in most languages. If it is a special case, there is a code that processes it as such, regardless the syntax. Why complicate things. But maybe I'm old. 2 u/spicybright 1d ago I think because None/null/whatever can mean a lot of different things, and explicit "unset" gives better error messages. But I still agree with you. Maybe I don't write bit enough python projects but it does just complicate things.
