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(); }
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.
