If I understand correctly, try passing self of parent to the the inner object 
when it's created. 

  class Inner
    def initialize( parent )
      @parent = parent
    end
  end

  class Outer
    def initialize
      Inner.new(self)
    end
  end

With any luck, in the future we will have a "caller" method that can refer to 
the parent object from Inner#initialize, i.e. without having to specifically 
pass self. (Personally I've always thought #object_parent should be built-in 
anyway.)
