description: return() call while iterator is in state executing
info: |
AsyncGenerator.prototype.return ( value )
1. Let generator be the this value.
2. Let completion be Completion{[[Type]]: return, [[Value]]: value, [[Target]]: empty}.
3. Return ! AsyncGeneratorEnqueue(generator, completion).
AsyncGeneratorEnqueue ( generator, completion )
...
4. Let queue be generator.[[AsyncGeneratorQueue]].
5. Let request be AsyncGeneratorRequest{[[Completion]]: completion,
[[Capability]]: promiseCapability}.
6. Append request to the end of queue.
...
AsyncGeneratorResolve ( generator, value, done )
...
2. Let queue be generator.[[AsyncGeneratorQueue]].
3. Assert: queue is not an empty List.
4. Remove the first element from queue and let next be the value of that element.
