|     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.
