I find it so sad that people wasted millions of hours and lines of code rewriting over and over basic constructs that should have been on the language in the first place. How many years before we finally get sum types?

It's not like your idea is bad, is that each abstraction eats in one of the fundamental strengths of Go (simplicity and compilation times).

Go was never simple in action. The fact that you'd panic a nil map but not a nil slice is a foot gun. It's a pretty big foot gun. It's just one of the many foot guns.
