description: A block-scoped binding is created (IfStatement with a declaration in both statement positions in eval code)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
flags: [generated, noStrict]
info: |
    The following rules for IfStatement augment those in 13.6:

    IfStatement[Yield, Return]:
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
        if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]


    13.2.14 Runtime Semantics: BlockDeclarationInstantiation

    [...]
    4. For each element d in declarations do
       a. For each element dn of the BoundNames of d do
          i. If IsConstantDeclaration of d is true, then
             [...]
          ii. Else,
              2. Perform ! envRec.CreateMutableBinding(dn, false).

       b. If d is a GeneratorDeclaration production or a FunctionDeclaration
          production, then
          i. Let fn be the sole element of the BoundNames of d.
          ii. Let fo be the result of performing InstantiateFunctionObject for
              d with argument env.
          iii. Perform envRec.InitializeBinding(fn, fo).
