While trying to write some OO Perl code I did something that didn't work. I quickly realised my mistake, and used a temporary variable. This irked me somewhat, so I've spent far too long trying to work out an alternative.

I was wondering if some knowlegable Monk may be able to suggest a better way.

Some sample code which demonstrates my problem: 

#!/usr/bin/perl
use strict;

package obj;

use vars qw($AUTOLOAD );

sub new {
    my $proto = shift;
    my $class = ref($proto) || $proto;
    my $self = { };

    bless ($self, $class);
    return $self;
}

sub AUTOLOAD {
    my $self = shift;
    my $attr = $AUTOLOAD;
    $attr =~ s/.*:://;
    return if $attr eq 'DESTROY';···

    $self->{uc $attr} = shift if @_;
    return $self->{uc $attr};
}

package main;

my $ob1 = obj->new;
my $ob2 = obj->new;
my $ob3 = obj->new;

$ob1->data(100);
$ob2->object($ob1);
$ob3->name('data');

my $temp=$ob3->name;
print $ob2->object->$temp;

What I'd like to know is if is possible to produce the same results without the need for the temporary variable $temp.

If anyone is interested, my initial attempt was:
    $ob2->object->$ob3->name;
