| description: Re-declaration of catch parameter |
| info: | |
| [...] |
| |
| This modified behaviour also applies to var and function declarations |
| introduced by direct evals contained within the Block of a Catch clause. |
| This change is accomplished by modify the algorithm of 18.2.1.2 as follows: |
| |
| Step 5.d.ii.2.a.i is replaced by: |
| |
| i. If thisEnvRec is not the Environment Record for a Catch clause, throw a |
| SyntaxError exception. |
| ii. If name is bound by any syntactic form other than a |
| FunctionDeclaration, a VariableStatement, the VariableDeclarationList |
| of a for statement, or the ForBinding of a for-in statement, throw a |
| SyntaxError exception. |
| flags: [noStrict] |
