Extension is observed when creation of variable binding would not produce an

has F as a BindingIdentifier would not produce any Early Errors for
body, 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.
