What specific section or headline is this issue about?

Return value

What information was incorrect, unhelpful, or incomplete?

A Promise that resolves to one of the following result objects:

{ async: false, value: 'ok' }
{ async: false, value: 'not-equal' }
{ async: false, value: 'timed-out' }
{ async: true, value: promise }

What did you expect to see?

From the current proposal, the result is an object, not a promise—i.e. if async: false, it actually operates synchronously. Also, "ok" should be part of the promise, not a string.

The result should look like this:

type Result =
  | { async: false; value: "not-equal" | "timed-out" }
  | { async: true; value: Promise<"ok" | "timed-out"> };
