This module provides a convenient way to perform cleanup or other
|
|
forms of resource management at the end of a scope. It is particularly
|
|
useful when dealing with exceptions: the Scope::Guard constructor
|
|
takes a reference to a subroutine that is guaranteed to be called
|
|
even if the thread of execution is aborted prematurely. This
|
|
effectively allows lexically-scoped "promises" to be made that are
|
|
automatically honoured by perl's garbage collector.
