 Class Precedence List
 .....................
 
 The "class precedence list" of a class is the list of all direct and
 indirect superclasses of that class, including the class itself.
 
 In the absence of multiple inheritance, the class precedence list is
 ordered straightforwardly, beginning with the class itself and ending
 with `<top>'.
 
 For example, given this inheritance hierarchy:
 
      (define-class <invertebrate> (<object>) ...)
      (define-class <echinoderm> (<invertebrate>) ...)
      (define-class <starfish> (<echinoderm>) ...)
 
 the class precedence list of <starfish> would be
 
      (<starfish> <echinoderm> <invertebrate> <object> <top>)
 
 With multiple inheritance, the algorithm is a little more complicated.
 A full description is provided by the GOOPS Tutorial: see  Class
 precedence list.
 
 "Class precedence list" is often abbreviated, in documentation and
 Scheme variable names, to "cpl".
