Devel::GlobalDestruction(3pm)				User Contributed Perl Documentation			     Devel::GlobalDestruction(3pm)

NAME
       Devel::GlobalDestruction - Expose the flag which marks global destruction.

SYNOPSIS
	   package Foo;
	   use Devel::GlobalDestruction;

	   use namespace::clean; # to avoid having an "in_global_destruction" method

	   sub DESTROY {
	       return if in_global_destruction;

	       do_something_a_little_tricky();
	   }

DESCRIPTION
       Perl's global destruction is a little tricky to deal with WRT finalizers because it's not ordered and objects can sometimes disappear.

       Writing defensive destructors is hard and annoying, and usually if global destruction is happenning you only need the destructors that free
       up non process local resources to actually execute.

       For these constructors you can avoid the mess by simply bailing out if global destruction is in effect.

EXPORTS
       This module uses Sub::Exporter so the exports may be renamed, aliased, etc.

       in_global_destruction
	   Returns true if the interpreter is in global destruction. In perl 5.14+, this returns "${^GLOBAL_PHASE} eq 'DESTRUCT'", and on earlier
	   perls, it returns the current value of "PL_dirty".
