+description: Extension not observed when creation of variable binding would produce an early error (switch statement) (IfStatement with a declaration in both statement positions in the global 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]
+        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
+        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]

+       F as a BindingIdentifier would not produce any Early Errors for script,
