No idea what that means.. Do you have a concrete example of what CPS allows and async/await doesn't?

I believe async/await means you have a single consumer (caller) and a single producer (callee) and only a single value will be produced (resolved).

With CPS you may send and receive many times over to whomever and from whomever you like.

In JavaScript you may write..

    const fetchData = async () => {
        // snip
        return data;
    }

    const data = await fetchData();

And in Go you might express the same like..

    channel := make(chan int);
    
    go func() {
        // snip
        channel <- data;
    }()
    
    data := <-channel

But you could also, for example, keep sending data and send it to as many consumers as you like..

    go func() {
        for { // Infinite loop:
            // snip
            channel1 <- data;
            channel2 <- data;
            channel3 <- data;
        }
    }()
