 Well, when I've seen it I've said "but it's #extend !!!" and I was
 surprised by this use of #include :-)))

 with extend it's just


   module Resource
      def use(*params, &blk)
         obj = new(*params, &blk)
         begin
            return yield(obj)
         ensure
            obj.close if obj.respond_to?(:close)
         end
      end
   end
