Yes, I realize it is pretty trivial to do it. Perhaps I do not understand
the purpose of the overridden System.Object.Equals method but I would have
thought that this should test for object equality rather than instance
equality for derived classes, since one could always test for instance
equality by casting both references to a System.Object.
