Subject: referring to variables in the scope outside the def

When defining a singleton method, I want to refer to variables in the scope
outside the def. Is it possible to do something like the following?

class C
  def initialize
    @child = Object.new
    s = self
    def @child.parent
      s # Wrong. But how do I refer to the instance of C?
    end
  end
  attr_reader :child
end

c = C.new
c == c.child.parent # Should be true.

Any hints? I think I'm missing a vital piece of magic here. Or maybe I'm
expecting too much Lisp-ness.
