# coroutines

I find myself needing something like this for use in while (true) loops because while (isActive) continues execution and doesn't throw:

@UseExperimental(InternalCoroutinesApi::class)
fun CoroutineContext.checkIsActiveOrCancelNow() {
    val job = get(Job)
    if (job != null && !job.isActive) throw job.getCancellationException()
}

This is quite useful in loops where I implement retrying.
The alternative to that coroutineContext.checkIsActiveOrCancelNow() call is to use if (isActive.not()) yield(), but I find that it doesn't communicate the intent well.

Do you think this should be integrated into kotlinx.coroutines? I'm personally inclined to open an issue there, but I want to know if I'm not alone first.
