// switch statement
switch operatingSystem {
case "darwin":
    fmt.Println("Mac OS Hipster")
    // cases break automatically, no fallthrough by default
case "linux":
    fmt.Println("Linux Geek")
default:
    // Windows, BSD, ...
    fmt.Println("Other")
}

// as with for and if, you can have an assignment statement before the switch value 
switch os := runtime.GOOS; os {
case "darwin": ...
}

// you can also make comparisons in switch cases

    case number == 42:
        fmt.Println("Equal")
    case number > 42:
        fmt.Println("Greater")
