      5 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 eval code in the global scope)

     12    ii. If replacing the FunctionDeclaration f with a VariableStatement that
     13        has F as a BindingIdentifier would not produce any Early Errors for
     14        body, then
     15    [...]

     17    B.3.5 VariableStatements in Catch Blocks
     18 
     19    [...]
     20    - It is a Syntax Error if any element of the BoundNames of CatchParameter
     21      also occurs in the VarDeclaredNames of Block unless CatchParameter is
     22      CatchParameter:BindingIdentifier and that element is only bound by a
     23      VariableStatement, the VariableDeclarationList of a for statement, or the
     24      ForBinding of a for-in statement.
