(description "@code{Guard} implements so-called @dfn{guards}. A guard is
something (usually an object) that \"guards\" a resource, ensuring that it is
cleaned up when expected.
Specifically, this module supports two different types of guards: guard
objects, which execute a given code block when destroyed, and scoped guards,
which are tied to the scope exit.")
