A named KnowledgeWorks CLOS class is defined by the macro
 def-named-kb-class which is syntactically identical to the Common Lisp  defclass  macro, and semantically identical with the exception that it adds a KnowledgeWorks mixin class   named-kb-object  if none of the superclasses already contains  it, and makes the default name for the objects be a symbol generated from the class name. Classes defined by  def-named-kb-class contain a name slot which those defined by  def-kb-class do not.
 The function  make-instance  can be given the initialisation argument  :name  to specify a name. If not specified, a default name is generated. All names must be distinct as regarded by  eq  . The function
 (get-kb-object <name>)retrieves the instance from its name. The function
 (kb-name <object>)returns the name of the given object.
