NAME

       Devel::GlobalDestruction - Provides function returning the equivalent of "${^GLOBAL_PHASE}
       eq 'DESTRUCT'" for older perls.

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
       happening 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::Progressive so the exports may be renamed, aliased, etc.
       if Sub::Exporter is present.

       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, detects it using the value of
           "PL_main_cv" or "PL_dirty".
