I heard that `std::mem` sounds scary to some people, and how it’s
described — “Basic functions for dealing with memory” — sounds even to
me like something that should be avoided, not even because it would be
unsafe, but because it is too low-level.
Let’s fix that by telling people about what they can actually find in
the module, without having to read all the individual item descriptions.
