    6. Let closure be FunctionCreate(kind, StrictFormalParameters,
       FunctionBody, scope, strict). If functionPrototype was passed as a
       parameter then pass its value as the functionPrototype optional argument
       of FunctionCreate.

        b. If next is an abrupt completion, set iteratorRecord.[[Done]] to true.
        c. ReturnIfAbrupt(next).
