 Another way :-)

c>  class Animal
c>    def initialize(name)
c>      if name == ""
c>        @name = "an unnamed #{self.class} "
c>      else
c>        @name = name
c>      end
c>    end

      def initialize(name = "an unnamed #{self.class} ")
         @name = name
      end

c>    def speak
c>      print @name, " says ", sound, "\n"
c>    end
c>  end

c>  class Horse < Animal
c>    def sound; "neigh";  end
c>  end


c>  aHorse = Horse.new("")

    aHorse = Horse.new

c>  aHorse.speak

c>  talking = Horse.new("Mr. Ed")
c>  talking.speak
