old code:

        code = <<-code
          def #{ name }!
            initializer = ObjectSpace._id2ref #{ initializer_id }
            self.#{ name } = initializer.call(self)
            @#{ name }
          end
        code
        compile[code]

new code:

        module_eval do
          define_method :"#{ name }!" do
            self.send :"#{ name }=", initializer.call(self)
            self.instance_variable_get :"@#{name}"
          end
        end
