NAME

Variable::OnDestruct - Call a subroutine on destruction of a variable.

VERSION

Version 0.03

SYNOPSIS

    use Variable::OnDestruct;

        on_destruct $var, sub { do_something() };
        on_destruct @array, sub { do_something_else() };
        on_destruct %array, sub { hashes_work_too() };
        on_destruct &$sub, sub { so_do_closures($but_not_normal_subs) };
        on_destruct *$glob, sub { and_even_globs($similar_caveats_as_subs_though) };

DESCRIPTION

This module allows you to let a function be called when a variable gets destroyed. The destructor will work not only on scalars but also on arrays, hashes, subs and globs. For the latter two you should realize that most of them aren't scoped like normal variables. Subs for example will only work like you expect them to when they are closures.

FUNCTIONS

This module contains one function, which is exported by default.

on_destruct $variable, \⊂

This function adds a destructor to a variable.
