C/C++ Users Journal October 2000 edition has an even better(?) idea using
templates that is pretty neat (and somewhat larger). They define an
elaborate template class variant_t and an ArguementList class that uses
it. It even allows type-safe access to the arguement list (and throws an
exception if the type you want doesn't match).
That way you can pass anything you like and it doesn't have to be
derived from some common class.
