TypeScript 5.2 introduces 'using', a keyword that disposes anything with a `Symbol.dispose` function upon leaving scope, making resource management easier.

      Discriminated unions have been In The Works™ 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.

        Yeah unfortunately tacking them onto a 20 year old language is not easy.

        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?

      This comment sounds like you’re having a stroke if we didn’t know the context.
