    6. If AssignmentRestElement is present, then
       a. Let status be the result of performing
          IteratorDestructuringAssignmentEvaluation of AssignmentRestElement
          with iteratorRecord as the argument.
    7. If iteratorRecord.[[Done]] is false, return ? IteratorClose(iterator, status).
    8. Return Completion(status).
