Hi,

when playing with overloaded stringification of objects, i noted the 
overload magic has disappeared in the DESTROY, but only if it's 
actually going out of scope.

Here's the relevant code, and the output.. note especially the last 
Dump;

[kane@coke ~/Documents/Perl]$ cat stringify_in_destroy
#!/usr/bin/perl -w

use strict;

{
     my $x = new Axe 'hack';
     $x->printme;
     print "X = $x\n";
     $x->DESTROY;
}

print "After block\n";

package Axe;
use Devel::Peek;

use overload q{""} => \&_stringify;

sub new {
     my $class = shift;
     my $str = shift;

     bless \$str, $class;
}

sub printme {
     my $self = shift;

     print "Printing $self\n";
     Dump $self;
}

sub _stringify {
     my $self = shift;

     return "I'm $$self";
}

sub DESTROY {
     my $self = shift;

     print "Destroying $self\n";
     Dump $self;
}

[kane@coke ~/Documents/Perl]$ perlc stringify_in_destroy
Printing I'm hack
SV = RV(0x5d07c) at 0x80d4c
   REFCNT = 1
   FLAGS = (PADBUSY,PADMY,ROK,OVERLOAD)
   RV = 0x80dc4
   SV = PVMG(0x72c40) at 0x80dc4
     REFCNT = 2
     FLAGS = (PADBUSY,PADMY,OBJECT,POK,pPOK)
     IV = 0
     NV = 0
     PV = 0x58180 "hack"\0
     CUR = 4
     LEN = 5
     STASH = 0x513f4     "Axe"
X = I'm hack
Destroying I'm hack
SV = RV(0x5d098) at 0x55aec
   REFCNT = 1
   FLAGS = (PADBUSY,PADMY,ROK,OVERLOAD)
   RV = 0x80dc4
   SV = PVMG(0x72c40) at 0x80dc4
     REFCNT = 2
     FLAGS = (PADBUSY,PADMY,OBJECT,POK,pPOK)
     IV = 0

   SV = PVMG(0x72c40) at 0x80dc4
     REFCNT = 2
     FLAGS = (PADBUSY,PADMY,OBJECT,POK,pPOK)
     IV = 0
     NV = 0
     PV = 0x58180 "hack"\0
     CUR = 4
     LEN = 5
     STASH = 0x513f4     "Axe"
After block
