 structures work -- this would violate STL principles.  E.g.
 std::list<> doesn't support random access iterators although it would
 technically be possible.
 
 Murray, is it OK to close this bug?

+The existence of the function gtk_tree_model_iter_nth_child() seems to
+hint of the possibility of random-access iterators. If the underlying
+GtkTreeModel is using a data structure that would allow for fast
+random access, then having a random-access iterator might be desirable.
+
+For the built-in GtkTreeModels (GtkTreeStore/GtkListStore), a
+random-access call would be O(n) because (from what I understand) they
+use linked-lists internally. However, for a custom GtkTreeModel, it is
+possible to have O(1) performance with a random-access iterator.
+
+You could implement a random-access iterator by doing the following:
+
+1) Get the index of the current iterator in the parent from the path
+using gtk_tree_model_get_path()
+2) Get the parent iterator of the iterator in question using
+gtk_tree_model_iter_parent()
+3) Add the given requested index to the current index and get the
+requested iterator using gtk_tree_model_iter_nth_child()
+
+I could write this and submit a patch if you guys think it would be
+useful.
