    GeneratorMethod :

    1. Let propKey be the result of evaluating PropertyName.
    2. ReturnIfAbrupt(propKey).
    3. If the function code for this GeneratorMethod is strict mode code,
       let strict be true. Otherwise let strict be false.
    4. Let scope be the running execution context's LexicalEnvironment.
    5. Let closure be GeneratorFunctionCreate(Method,
       StrictFormalParameters, GeneratorBody, scope, strict).

    1. Let status be FunctionDeclarationInstantiation(F, argumentsList).

    23. Let iteratorRecord be Record {[[iterator]]:

    24. If hasDuplicates is true, then

    25. Else,
        b. Let formalStatus be IteratorBindingInitialization for formals with
           iteratorRecord and env as arguments.

       b. If iteratorRecord.[[done]] is true, then
