You can use `coroutineScope` in your function body so the caller doesn’t need to pass one in, and it t would be more idiomatic to use `launch` instead of `async` since the timing coroutine doesn’t need to return a value. 

ah, interesting. So coroutineScope is essentially a handy function to “create or reuse existing coroutine scope”?

…and a suspend function in and of itself might not have a coroutine scope, so I guess it makes the function more ergonomic

`coroutineScope` has pretty good docs, but yea it creates a "child" coroutine and waits for it to finish (including any coroutines that it launches)
