Async Assists

With combined, you can't just return a promise from a method. It's too complex for that type of problem because combined is trying to solve a much more complicated problem. And I feel like if you're trying to do reactive programming with async sequences, like with when you can do a for loop and you do for await value in sequence, we can start doing now withync stream but they look quite a bit different. With combined, because you have the councilable and you have the subscriptions and it's all kind of managed in that way, it becomes more natural.
