hello monks, i'm having a problem trying to reference a subrotine that is inside a package that maintains an ISA relationship with other package. after here i'm gonna refer to the packages as classes (because that is the conceptualization i'm using) the subroutine (called parse_tag) is declared in the super class (called gadget), this class does not EXPORT any of it's methods (because i want them to be only accesible from the class and subclasses scopes). here's the code of both classes (simplified): 
package gadget;

use vars qw($VERSION $CLASS);
$CLASS = __PACKAGE__;
$VERSION = "0.01";

#Generic method, it can (in theory ;-) return an instance of any subcl
+ass
sub new {
   #do initialization stuff
}


sub parse_tag {
        my ($twig,$elem) = @_;
        #do stuff 
}

and the child class code: 
package test;
use gadget;
use vars qw($VERSION $CLASS);
$CLASS = __PACKAGE__;
$VERSION = "0.01";

BEGIN {
        @test::ISA = qw(gadget);
        @test::ISA = qw(Exporter);
        @test::EXPORT = qw(parse_tag);
}

sub new {
        my $class = shift || $CLASS;
        my $obj = $class->SUPER::new($class);
        $obj->{test_attr} = "atributo de prueba";
        return($obj);
}

sub test_stuff {
        my $self = shift;
        foreach my $a (@_){
                print "($self) ARGUMENTO: $a\n";
        }
}

i don't have problems calling the subroutine from within the subclass (called test), the problem is when i load the subclass (test) into another module and try to make a reference to it, here's the code that causes the problem: 
require "test.pm";
$twigroots->{test} = \&{test::parse_tag};

[download]
in here i get this message: Undefined subroutine &test::parse_tag
i know that is some referencing stuff, but i'm kind of confused, any help will be greatly appreciated.
thanks.


ignorance, the plague is everywhere
