So the user code will at least compile (unlike with Marc Mutz's approach), 
but algorithms that previously completed in O(n) will now complete only in 
O(mn) (and of course this multiplies on: if you were inserting into a QList 
in a loop, it goes from O(n²) to O(mn²)), which is kinda ironic for a change 
designed to "improve performance".
