    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.

    2. If iteratorRecord.[[done]] is true, let v be undefined.
    3. If Initializer is present and v is undefined, then
       a. Let defaultValue be the result of evaluating Initializer.
       b. Let v be ? GetValue(defaultValue).
    4. Return the result of performing BindingInitialization of BindingPattern
       with v and environment as the arguments.
