   *  This means that we can make certain assumptions to optimize the universe.
   *  For example, we may auto-initialize symbols on flag and annotation requests
   *  (see `shouldTriggerCompleter` below for more details).
   *
   *  On the other hand, this also means that usage scenarios of the universe
   *  will differ from the conventional ones. For example, we have to do additional cleanup
   *  in order to prevent memory leaks: http://groups.google.com/group/scala-internals/browse_thread/thread/eabcf3d406dab8b2.
