Alternative to label

Get out of a for/select loop without using labels:

func main() {
 
OUT:
    for {
        select {
        case ... ):
            ...
        default:
            break OUT
        }
    }
    ....
}

Refactoring out the for loop:

func main() {
    ...
    doSomething()
    ...
}

func doSomething() {
    for {
        select {
        case ...:
            ...
        default:
            return
        }
    }
}
