Does this work? I don't have Ruby handy:

class SuperProxy
	def initialize(obj)
		@obj = obj
		@class = obj.class.superclass
	end

	def method_missing(sym, *args, &blk)
		@class.instance_method(sym).bind(obj).call *args, &blk
	end
end

class Object
	def parent
		@proxy = SuperProxy.new(self) unless @proxy
		@proxy
	end
end


Apologies if there are formatting errors, I'm on webmail.
