This syntax has been borrowed from other languages and is tried and true. I feel that the author intuited that something like this would be nice, but wasn't aware of async/await and so proposed something that only kind of vaguely points in the right direction. I don't think he's wrong that something like this would be nice, but async/await is a much more robust way of dealing with this!
