Maybe by monkey patching DESTROY?

use strict;
use warnings;

package Blubb;

sub new {
   my $this = bless {a=>42};
   $this->{circular} = $this;
}

sub DESTROY {
   warn "DESTROY";
}

package MAIN;

my $b = Blubb->new;


{
   no warnings 'redefine';

   my $orig= \&Blubb::DESTROY;

   *Blubb::DESTROY = sub {
      $orig->(@_);
      warn "END";
   };
}
