This module implements so-called "guards". A guard is something
(usually an object) that "guards" a resource, ensuring that it
is cleaned up when expected.

It is similar to eval {} blocks, except it's faster, and catches everything,
including direct calls to exit and the like. Prerequisite to Coro.


Different from Scope::Guard and Sub::ScopeFinalizer, which actually
implement dynamic, not scoped guards, and have a lot higher CPU,
memory and typing overhead.
