ABSTRACT
This module allows you to register subroutines to be executed when the scope they were registered in, has been left.
DESCRIPTION
POST
POST
takes a reference to a subroutine or a subroutine name and will register that subroutine to be executed when the scope is left. Note that even if the scope is left using die(), the subroutine will be executed.
EXPORT
None by default. POST can be exported if so required.
