Cool. Maybe "stop_using" would be a better name than "close":

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