    17. For each element d in lexDeclarations do
        a. For each element dn of the BoundNames of d do
           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).

    14.1.20 Runtime Semantics: InstantiateFunctionObject

    FunctionDeclaration : function ( FormalParameters ) { FunctionBody }

    1. If the function code for FunctionDeclaration is strict mode code, let
       strict be true. Otherwise let strict be false.
    2. Let F be FunctionCreate(Normal, FormalParameters, FunctionBody, scope,
       strict).
    3. Perform MakeConstructor(F).
    4. Perform SetFunctionName(F, "default").
    5. Return F.
