description: Extension is observed when creation of variable binding would not produce an early error (try statement) (Funtion declaration in the `default` clause of a `switch` statement in the global scope)

B.3.3.2 Changes to GlobalDeclarationInstantiation
|

|
|
|
||
|
|
[...]
|
||
|
|
b. If replacing the FunctionDeclaration f with a VariableStatement that has
|
||
|
|
F as a BindingIdentifier would not produce any Early Errors for script,
|
||
|
|
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.
