Example in the context of an Activity or Fragment:

suspend fun getResultForIntent(intent: Intent) {
    when(result = getResultFor(intent)) {
        is Result.Ok -> // whatever
        is Result.Cancelled -> // whatever
    }
}

onActivityResult is deprecated now. Do you think we can build something similar for the new Activity Results APIs?

For sure! I'll check that, I think this will be even simpler ;)
