No, it's wrong way. Good library MUST give to developer fast routines!
E.g. for GTK is best solve of the problem would be inherite all objects from
GList! In this case you can easy create list inside ListStore and TreeStore
without any fear and give users access to UNBREAKABLE iterators.

We not like O(N) routines :-)
