You mean 'with'? That's not actually destruction, it just does one of
the same jobs that deterministic destruction is used for (RAII). It
doesn't, for instance, have any influence on memory usage, nor does it
ensure the destruction of the object's referents. But yes, it does
achieve (one of) the most important role(s) of destruction.
