I think there isn't general way. The meaning of deep copy depends on
target object, so we have define such method for each class. 

Marshal.dump is another option, but not perfect. 

  class Object
    def deep_copy
      Marshal.load(Marshal.dump(self))
    end
  end

Maybe, deep copy is not suitable operation for an object.
