| description: Extension not observed when creation of variable binding would produce an early error (IfStatement with a declaration in both statement positions in eval code) |

| es6id: B.3.4 |
| 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] |
