What does `std:unique_ptr` add is not "already trivially possible"? It
adds vocabulary, so that everyone can easily see and digest what your
intent is.

Why does everyone need to roll their own "generic_cleanup" class when
there could be a simple standard-defined one? And yours is horribly
inefficient, as it uses `std::function`.
