           i. If IsConstantDeclaration of d is true, then

           ii. Else,
               1. Perform ! envRec.CreateMutableBinding(dn, false).
           iii. If d is a GeneratorDeclaration production or a
                FunctionDeclaration production, then
                1. Let fo be the result of performing InstantiateFunctionObject
                   for d with argument env.
                2. Call envRec.InitializeBinding(dn, fo).

    14.4.12 Runtime Semantics: InstantiateFunctionObject

    GeneratorDeclaration : function * ( FormalParameters ) { GeneratorBody }

    1. If the function code for GeneratorDeclaration is strict mode code, let
       strict be true. Otherwise let strict be false.
    2. Let F be GeneratorFunctionCreate(Normal, FormalParameters,
       GeneratorBody, scope, strict).
    3. Let prototype be ObjectCreate(%GeneratorPrototype%).
    4. Perform DefinePropertyOrThrow(F, "prototype",
       PropertyDescriptor{[[Value]]: prototype, [[Writable]]: true,
       [[Enumerable]]: false, [[Configurable]]: false}).
    5. Perform SetFunctionName(F, "default").
    6. Return F.
