    BindingRestElement : ... BindingIdentifier

    1. Let lhs be ResolveBinding(StringValue of BindingIdentifier,
       environment).
    2. ReturnIfAbrupt(lhs).
    3. Let A be ArrayCreate(0).
    4. Let n=0.
    5. Repeat,
       [...]
       c. Let nextValue be IteratorValue(next).
       d. If nextValue is an abrupt completion, set iteratorRecord.[[done]] to
          true.
       e. ReturnIfAbrupt(nextValue).
