Continue

The continue keyword goes to the next turn.

loop {
    sleep(1)
    continue
    println("hi") // never called
}

To go to the next turn of an outer loop, use a label:

'outer: loop {
    loop {
        continue 'outer
    }
}

In a mathematical loop, continue skips the current item:

fn main() {
    list := [1, 2, 3, 4]
    println(sum i {
        if i == 2 { continue } // skip `3`
        list[i]
    }) // prints `7`
}
