Let me take a step back. Do we need a list container that is always
indirect regardless of
the element type and uses implicit sharing?

If I start using QArrayList<indirect_type> today, and it's immediately
deprecated, what
should I use instead? vector<unique_ptr<indirect_type>>? That doesn't
do implicit sharing,
so I can't pass it by value into slots.
