Is there a better way to “launch flow collection but suspend until the collection is ready”?
Without this workaround (i.e. .onEach { … }.launchIn(…)) elements can be missed if they’re emitted shortly after this.

launch(start = CoroutineStart.UNDISPATCHED) {
    collect { action(it) }
}

That does something very different 🤔
It delays the start of the collection instead the start of the emission.

[ephemient]

the launch doesn't return until collect suspends, after which it is safe to start emitting. is that not what you want to wait for?

What is the scope of that?
