  3. Let errors be a new empty List.

  8. Repeat,
    a. Let next be IteratorStep(iteratorRecord).
    b. If next is an abrupt completion, set iteratorRecord.[[Done]] to true.
    c. ReturnIfAbrupt(next).
    d. If next is false, then
      i. Set iteratorRecord.[[Done]] to true.
      ii. Set remainingElementsCount.[[Value]] to remainingElementsCount.[[Value]] - 1.
      iii. If remainingElementsCount.[[Value]] is 0, then
        1. Let error be a newly created AggregateError object.
        2. Set error.[[AggregateErrors]] to errors.
        3. Return ThrowCompletion(error).
