Anyway, there is a pragmetic advantage in having a function return a pointer. It allow us to mix test+access with one call, as in: if ( T* p = opt.get() ) but this functionality can be provided but a separate methods called get_ptr() given the expected meaning of a method named get() for something that is a value container.
