Is there anything like 'daemon coroutine' in coroutineScope that will be cancelled if other things in it are completed? Normally tasks running in launch in it will cause coroutineScope not to return.

one possibility:

runBlocking {
    val job = Job()
    launch(job) {
        while (true) yield()
    }
    launch(job) {
        delay(5_000)
    }

    delay(100)

    job.cancel()
}
// done in 100ms

I asked this because I was lazy to write `.cancel()`;
However this seems quite good.

Maybe I could use simple try .. finally...

you shouldn't need try-finally, an exceptional coroutine termination automatically cancels children
