Glad to meet you here, actually the questions are not which is faster, why use my library or your library…etc, and i did’t invent "some better idea”, the question is why not check other languages first, when there’re nice solutions already there.

> To be frankly, I can't read your doc in just 5min, it's a little obscure to me. Please don't stick on performance or internal complexity, it's not the bottleneck. The internal implementation of a library may be complex, but that's not what the end users care, most people use one thing before full understand how it works. In your opinion, does it means everyone should full understand the kernel of the linux before using it? If everyone does it, most of them will find some part of the linux is as bad as what you think about promise. If they take time to reinvent every so called not good enough part of it, they won't even have time to enjoy a movie, because the world is full of little flaws.
> You say your lib is much simpler than promise. Promises/A+ have only one api: `then`, you have 4: `go`, `next`, `guard`, `freeze`. The purpose of promise is let people work happily without knowing the internal state of it, and it doesn't constrain the type of the error, and give users the freedom. It's easy to see that you add more rules than promise. I can't say your thoughts is bad or wrong, but what the points you say promise is bad are just not good enough to persuade me.
> And I predict that as you learn more you will find your Action is still as bad as promise, it's may 10% better, but it's still a bad way to handle the real async world. I've seen a lot of libs like yours, and I created something alike when developing my own promise lib, we need a mind blow idea, not a little better idea.
