I think he's wanting to know if it's possible to call a different method
of the superclass than the method that the interpreter is in. For example,

class A
  def zoo
    puts "in zoo"
  end
end

class B < A
  def hoo
    super.zoo
  end
end

b = B.new
b.hoo


will not work -- you must explicitly define method #zoo in class B in
order to call the super version of it in class A. Is there a way to make
the above code work, short of defining zoo in B? I'm curious about this
also.
