It isn't what scoped_ptr is supposed to do. If you are looking for a smart
pointer with transfer of ownership you already have std::auto_ptr.
boost::scoped_ptr does not transfer ownership. If you give boost::scoped_ptr
a pointer, it will delete it (notice that even reset deletes the pointer).
Another view is that providing swap is an optimization over the std::swap
already available (as in faster, but with the same semantics), but you cannot
use std::swap with boost::scoped_ptr
