Before, an attempt to delete a parameter in a function that used the arguments object in any way would succeed with true and delete both the parameter and the corresponding arguments object property. Now, an attempt to delete such a parameter does not delete and evaluates to false. Parameters can be deleted, as before, from functions that use the arguments object, by deleting the corresponding arguments object property (this is a spec violation).
