Inserts stuff before, after, or instead range r, which must
be a valid range previously extracted from this array. stuff
can be a value convertible to bool or a range of objects convertible
to bool. Both stable and non-stable version behave the same and
guarantee that ranges iterating over the array are never invalidated.
