Sorry David, your a little late to make claims on that one. If you read my AOP 
RCR (which by the way I think I've plugged like six times now) you would 
notice that I offer:

  wrap w
    super
    print "W"
  end

as a backup alternative to my primary proposal, which I belive to be a far 
superior:

   class C
     def x
       puts "how are you?"
     end

     def x
       puts "hello"
       super
       puts "goodbye"
     end
   end

Before anyone looks at this and crys "foul!", read the dang RCR.
