Code compiles with unused var block

[Danny Hart]

Hello all,

Very new gopher here (also first time using Groups, please excuse poor etiquette).  I was curious why the following basic program compiles with an unused var. Is it the case that the compiler only complains about unused vars in a function body?

package main

import (

"fmt"

)

var (

x int

)

func main() {

fmt.Println("Hello, playground")

}

You are correct sir, and unfortunately, go vet doesn't find it either. 

But if you lint your code with golangci-lint (https://github.com/golangci/golangci-lint) 

the deadcode linter will find it for you.
