I'm losing sight of the goal here.  What's the advantage of this kind
of indirectness and extra work, when you can just write the code?

  class B < A
    def doit
      super
      @y = 10
    end
  end

Normally I would assume that a small example is encapsulating
something that one would want to do one a larger scale, but I'm not
sure what that would be here.  (By "here" I mean the question raised
in the whole thread, not just this example.)
