+    (e.g. insert() or remove()) is called. When stability and iterator-like
+    functionality is required, you should use indexes instead of iterators as
+    they are not tied to QList internal state and thus do not get invalidated.
 
     In addition to QList, Qt also provides QVarLengthArray, a very
     low-level class with little functionality that is optimized for
     speed.

-    with references to its own values. Doing so will cause your application to
