  Depends... it's not that obvious. One should put the question: could the  
member exist outside/wihtout the class? If it could, a pointer might be a  
better solution.

  We have also Qt's collection classes:

  Now which ones should be used? :D

  I don't see any object that _should_ be instanciated in such quantities  
and all objects the same. If this is a problem, we should document it.

  This is what the people at Sun thought, and invented Java. :)

  LOL. You can't get away witout pointers, if you don't write your memory  
manager.

  I've stated my opinion before: let's have something maintainable, then  
optimize / work on high efficiency. I'd say if it's good enough for now,  
let's not change it.
