Subject: methods that affect subsequently defined methods

Hi,

I want to implement methods like Ruby's protected that will effect some
aspect of the subsequently defined methods. For example, I want write
sth like follows:

class Test
   authorize_for :ROLE1, :ROLE2
    def method1
      ...
    end

    def method2
      ...
    end

  authorize_for :ROLE3
    def method3
      ...
    end
end


In the def. on authorize_for method, I can use a global var to hold the
parameters passed and then use then in method_added callback.
However, once the class definition end, I no longer need those global
variables
and I couldn't find a way to mark them for gc (set to nil).

I need a way to be informed about the end of the class definition. I
considered set_trace_func but because there is no way to chain or
restore trace funcs after set, so that is not really an option.

I also checked for class_added callback, but according to the Ruby list,
it's been refused because of lack of concrete usage.

Is there any other way to accomplish this?
