+description: A block-scoped binding is created (IfStatement with a declaration in the second statement position in function scope)
+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]

+    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).
