Node.js [ ... ] most async code is invoked with "await"

I think this might be caused by a lack of complementary programming concepts, such as actors.

Having worked with C# and the Orleans actor framework I found that I'm now using more complex async constructs, such as await Task.WhenAll() and async Linq statements that actually make code run more efficient.

Adding async and actors together to the Swift language seems like a very good idea to me.
