访问同一文件/包中的全局变量

Consider the following code

package main

import (
    "fmt"

)

var global int = 40

func main() {


    var global int = 30
    fmt.Println(::global) // In C++ this would print 40

}

How can I print the global variable value 40? There are posts on SO about accessing global variables from different packages but I could not find anything about accessing globals within the same file/package

How can I print the global variable value 40?

By not shadowing it. Or if you absolutely must shadow it (but why would you?), re-assign it to another variable first.

func main() {
    originalGlobal := global
    var global int = 30
    fmt.Println(originalGlobal)
}
