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.
