Golang在带有通道的goroutine中暂停循环

Question

I have a function that is launched as a goroutine:

func (bt *BlinkyTape) finiteLoop(frames []Frame, repeat int, delay time.Duration) {
    bt.isPlaying = true
L:
    for i := 0; i < repeat; i++ {
        select {
        case <-bt.stop:
            break L
        default:
            bt.playFrames(frames, delay)
        }
    }
    bt.isPlaying = false
}

This function uses channels so it is possible to break the loop (loop can be finite or infinite)

What I would like to implement is a way to pause the execution of the loop and of course being able to resume it.

I was thinking to add another case to the select condition where I listen on another channel pause. If the case is executed, it enter in a new infinite loop that does nothing. Then it will need the same system as previously with a resume channel to break this loop.

What do you think ? Is there a better way to achieve what I need ?
