Syntax to call ancestor's virtual method explicitly

If you only want to define the traversal once on a particular superclass, why not make it a different method that isn’t obscured by subtypes?

class S1
  def my_method_S1
    puts "S1"
  end

  def my_method
    my_method_S1
  end
end

class S11 < S1
   def my_method
     puts "S11"
     my_method_S1
   end
end

In general, though, I agree that you should consider whether accessing a particular superclass implementation of an obscured method is really what you want.
