| description: Extension is observed when creation of variable binding would not produce an early error (try statement) (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] |

| B.3.3.3 Changes to EvalDeclarationInstantiation |
| |
| [...] |
| ii. If replacing the FunctionDeclaration f with a VariableStatement that |
| has F as a BindingIdentifier would not produce any Early Errors for |
| body, then |
| [...] |
| |
| B.3.5 VariableStatements in Catch Blocks |
| |
| [...] |
| - It is a Syntax Error if any element of the BoundNames of CatchParameter |
| also occurs in the VarDeclaredNames of Block unless CatchParameter is |
| CatchParameter:BindingIdentifier and that element is only bound by a |
| VariableStatement, the VariableDeclarationList of a for statement, or the |
| ForBinding of a for-in statement. |
