Speculations. I've never seen someone do it. I never do it. I always use
pointer operations to manipulate large chunks. That's under the assumption
that whoever used move_ptr<T[]> instead of a vector<T> is performance and
overhead sensitive. The optimizers aren't very good at such code because of
their conservative aliasing assumptions.
