(description "This package provides a RAII scope guard that will run a
given closure when it goes out of scope, even if the code between panics
(assuming unwinding panic). Defines the macros @code{defer!},
@code{defer_on_unwind!}, @code{defer_on_success!} as shorthands for guards
with one of the implemented strategies.")
