    Yeah, insisting on things like a variable being used will result in people using work arounds. It won’t result in people not doing it.

    Then, because people trust the language to police this rule, the work-arounds and debug code will get committed.

    func main() {  
        test := true  
    }  
    

    Oops, golang doesn’t like that.

    func main() {  
        test := true  
        _ = test  
    }
    

    Perfectly cromulent code.

    If they really wanted to avoid people having unused variables, they should have used a naming convention. Any variable not prefixed by “_” or “_debug_” or whatever has to be used, for example. Then block any code being checked in that still contains those markers.
