Ok, but you cannot have something like

	def #{method}(*args, &block)
	  attr :#{method}
	  @#{method} = #{old_method}(*args, &block)
	end

right? (attr not method in your class but in Module...) Or can you do it
by going into node.c/eval.c et al and define a rb_singleton_attr similar
to rb_attr but with rb_add_method substituted for (your newly defined!)
rb_add_singleton_method? This might not make any sense since I haven't
studied Ruby internals...
