Discriminated unions have been In The Works(tm) for quite a while. I believe they were cut from the C# 12 roadmap. But maybe C# 13?

I think a source-generation based approach similar to OneOf isn't unlikely.

It's great to see it being worked on but there is a long way to go.

Does using function as a const? Meaning: when a using variable is declared, is it immutable?
