As we are coming closer to release we'll need to finalize/cleanup APIs of kotlinx.coroutines, even though they are experimental. Let me float an idea. The functionality of defer {...} .await() is very similar to C#/JS/Dart `async`/`await` pair. The key difference is that in C# it returns Task, in JS it returns Promise, in Dart it returns Future, and in Kotlin it returns Deferred. So, the idea is to rename defer to async to fall in line with everybody else on this one aspect. Naming it async also makes writing async-style functions somewhat more natural:

// runs the code in the background thread pool
fun asyncOverlay() = async(CommonPool) {
    // start two async operations
    val original = asyncLoadImage("original")
    val overlay = asyncLoadImage("overlay")
    // and then apply overlay to both results
    applyOverlay(original.await(), overlay.await())
}

What do you think? Shall we name it async?
