What happens when this program is built and run?

package main

import "fmt"

func main() {
    x := 5
    fmt.Println("hi")
}

It does not compile

Expecting hi: Go has no warnings, and a local variable that is declared but never read stops the build with declared and not used: x.
Expecting the problem to show up at run time: an unused variable is found by the compiler, so no program is built and nothing runs.
