Looks sort of like our procedural language, except that instead of having a "pool" of functions, functions can be "member functions" of a class. In order to do this "all the way", it seems like we will need all instances to appear in their parent classes -- Select people.average_age() should hit all instances of people, even those that have been subclassed into teachers, police, lawyers, etc. Ocie Mitchell
