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]
