It is NOT equivalent, the SET FILTER stays in effect after the operation has been performed. This is a negative side effect that should be avoided. Many of the SET commands are dangerous because they can change the way that code is evaluated and they can change at anytime durring program execution. I would prefer some sort of scoped construct that automatically resets the previous setting automatically.
