This is just a different flavour of coloring. You would now have
functions that have "async" and functions that don't have "async".

a coroutine, it will spawn one for us, blocking until it returns. If we are=
 already inside a coroutine, then it blocks until the coroutine completes.

s literally just sugar over the currently proposed RFC, as you'd have to re=
turn Coroutines and await them anyway, but this is actually more type-safe.

At this point you need to know that a function is `async` because you
need to know if you need to call `await` on it. Without coloring, you
don't have this problem.

Let me see if I can find some time to create some examples using
ReactPHP on Github and then we can explore some additional syntax
there to see what it would feel like as a developer?
