generic function



Is there way to define a generic function which will specialize
based on the number of arguments passed. For example, I'm trying
to do the following:


(DEFGENERIC foo (@OPTIONAL bar)
)


(DEFMETHOD foo ()
  ;; No arguments
  <do some stuff>)


(DEFMETHOD foo (bar)
  ;; One argument
  <do something different>)


					Thanks
