    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.

       FormalParameter using iteratorRecord and environment as the arguments.
