My common way to program these classes is with shared_ptr actually.
Yes, it does require copy ctor and op= if deep copy semantics are
needed but that's rare (in my experience anyway) and the benefit of
shared_ptr is that you have complete control over the memory
allocations, all done in the cpp file completely decoupled from the
