I think TypeScript has a pretty good type system, and it's not too hard to learn. Adding sum types (i.e. enums or tagged unions) to Go would be a huge improvement without making it much harder to learn. I also think that requiring nullability to be annotated (like for primitives in C#, but for everything) would be a good feature for a simple type system. (Of course that idea isn't compatible with Go for various reasons.)
I also think that even before "proper" generics were added, Go should have provided the ability to represent and interact with "a slice (or map) of some type" in some way other than just
interface{}. This would have needed dedicated syntax, but since slice and map are the only container types and already have special syntax, I don't think it would have been that bad.
