So, you mean that this thunk is produced by the async function, and the await keyword will run it asynchronously?

In other words, print produces a thunk, and print_point also produces a thunk, and when await is used on the later, it is executed asynchronously, which will execute the print also asynchronously. So we end up with 3 different execution context: the main one, a one for each "await"?

What is the point of this, as opposed to executing the thunk asynchronously right away? Also, how does one get the result?

From the point of view of print_point await executes the thunk synchronously, print_point execution stops and awaits for print to finish it work. But a callee of print_point might want it to run print_point asynchronously, so print_point is an async fn, and callee can do something more creative then to await.

Thank you.

So, it seems I had understood the principle the way you explain it, but the code comment on print_point (as I indicated in the top of this thread) isn't saying that.
