    BindingRestElement : ... BindingPattern

    1. Let A be ArrayCreate(0).
    [...]
    3. Repeat

       b. If iteratorRecord.[[done]] is true, then
          i. Return the result of performing BindingInitialization of
             BindingPattern with A and environment as the arguments.

    SingleNameBinding : BindingIdentifier Initializer_opt

    [...]
    3. If iteratorRecord.[[done]] is false, then
       a. Let next be IteratorStep(iteratorRecord.[[iterator]]).
       b. If next is an abrupt completion, set iteratorRecord.[[done]] to true.
       c. ReturnIfAbrupt(next).
       d. If next is false, set iteratorRecord.[[done]] to true.
       e. Else,
          i. Let v be IteratorValue(next).
          ii. If v is an abrupt completion, set

    4. If iteratorRecord.[[done]] is true, let v be undefined.
