Everyone else has covered the part related to runes, so I am not going to talk about that.

However, there is also a question related to switch not having any arguments. This is simply because in Golang, switch without an expression is an alternate way to express if/else logic. For example, writing this:

t := time.Now()
switch {
case t.Hour() < 12:
    fmt.Println("It's before noon")
default:
    fmt.Println("It's after noon")
}

is same as writing this:

t := time.Now()
if t.Hour() < 12 {
    fmt.Println("It's before noon")
} else {
    fmt.Println("It's after noon")
}
