    2. Let iteratorRecord be Record {[[Iterator]]: iterator, [[Done]]: false}.
    3. Let status be the result of performing
       IteratorDestructuringAssignmentEvaluation of AssignmentElementList using
       iteratorRecord as the argument.
    4. If status is an abrupt completion, then
       a. If iteratorRecord.[[Done]] is false, return ? IteratorClose(iterator, status).
       b. Return Completion(status).
