If you’ve been writing Go for a few years, your code has layers. There’s an interface{} from before any existed, a for i := 0; i < n; i++ from before range over integers, some x := x inside a loop to dodge the famous loop variable problem, and more than one chained if that today would be a min(). None of that is wrong. The language simply moved on and the code stayed where it was.
