Subject: where's the best place to dynamically add singleton method?

Hi,

If I've got a simple bit of initialisation code

    def initialize( blah )
      @listener = Blah.new blah
    end

and I'd like to add a singleton method to instance (because I don't want to monkey patch the Blah library) where's the best place to do that? I know I could do:

    def initialize( blah )
      @listener = Blah.new blah
      def @listener.my_mental_method
        self.give_it_up! "quickly"
      end
    end

but is this a good place to do it, or is there something more eloquent/perfomant? I'd like all instances, wherever they are created, to have this method, so is there a better way altogether?

Just wondering.

Regards,
Iain
