is there a way to wait for not yet started coroutine? I want to achieve something similar to `yield` but with the coroutine that'll be started in the future

I don't get what you mean by something similar to `yield()`? are you talking about the Sequence `yield()` or the top-level `yield()`?

regardless, it sounds like you probably want to use `CompleteableDeferred`

thanks! Will checkout completable deffered

What about a call to `CoroutineScope.async(start=LAZY)`?

This will return a `Deferred&lt;T&gt;` and the Coroutine won't yet be running. It will start only after calling `await()` , `start()` (and some other methods) on it.

oo that's cool, it's really close to something that I wanted to achieve, thanks!
I was trying to avoid having some handle/object on coroutine that needs to do the waiting and was wondering if it can be automagically done through some await or yield mechanism under the hood. But I guess it's close enough

Coroutines try to stop being automagical beyond the `suspend` keyword :)

good point, I guess it's better to keep things simple :slightly_smiling_face:
