The i is scoped differently in clojure than in golang so it doesn't have the same potential pitfall. I think golang people consider their scoping here a mistake (and have tooling to check it?).

C# had the exact same pitfall and it was recognised years ago. It's unfortunate that it made it in to Go.

Did they introduce a language solution for it in C#?

C# 5.0 is changing the behavior of the loop variable to be logically inside the loop [0].

The Go race detector will generally catch this mistake at runtime.
