  15. Although Aaron doesn't explicitly say so, BASIC doesn't need a 
  16. garbage collector because it adopts a philosophy of copying on
  17. assignment.  This is a very expensive solution to avoiding GC
  18. of course.  It also doesn't help when you add shareable store
  19. to the language (e.g. Pascal pointers).
