I’d kill for union types as well.

… and pattern matching. Maybe just some extensions for `switch`.

… and one of the `try` proposals.

That having been said… I do appreciate that Go has gotten where it is today by being radically simple, and that a lot of extreme care needs to be done to add new features to the language. It’s hard to draw a firm line in the sand. I feel like all of these features would work great together, though; it’d enable Go to do something like `Result` in Rust with few language-level changes.

I even remain somewhat skeptical about generics, but I am hopeful.
