Additionally, UniquePtr is best used by threading it through interfaces, beyond just
immediate use sites. Rather than returning a raw pointer, code should return UniquePtr
instead. Rather than extracting a raw pointer to pass to a method, code should pass
Move(ptr) instead, and that argument should be a UniquePtr&&.
Only UniquePtr's own copy and assignment operators should take
UniquePtr&&. Other call sites should either take const UniquePtr& (if
they will not take ownership of the pointer), UniquePtr& (if they may or
may not need to take ownership of the pointer) or UniquePtr (if they
will take ownership of the pointer).
