The point is to have an object that isn't used in any way either as an object or as a value, boolean, string, or number. This is useful when testing things like Carp, Data::Dump::Streamer, etc. Anything which may find itself attempting to peek inside something that may be covered in arbitrary perl magic. This is an object which is covered in magic which complains loudly if you trigger any of it.
