Hi monks. Been programming Perl for several years but just stumbled upon Moose. Anyway, I have a script (wget.pl) that instantiates an object of a class (Wget.pm) that uses a role (Transfer.pm). The problem is when I pass a hash ref to Wget->new(), it's not being received correctly. Here is the relevant parts of the code.

wget.pl 

use Module::Load;

my $class = 'DTF::Wget';
load $class;
my $adapter = $class->new( 'input_line' => $input_line, 'dl_base_dir' 
+=> $dl_base_dir, 'report_file' => $report_file );

Wget.pm 

package DTF::Wget;
use strict;
use warnings;
use Moose;

with 'DTF::Transfer';

[download]

Transfer.pm 

package DTF::Transfer;
use strict;
use warnings;
use Moose::Role;

sub BUILD {}

after 'BUILD' => sub
{
    my $self = shift;

    die scalar(keys %$self);
}

If all worked, the die statement in the role would print 3, since I passed 3 key-value pairs to the constructor of the class that uses the role. However, it prints 0. $self has absolutely nothing. I tried several variations of this, including moving the BUILD to Wget.pm. The result is always the same - $self is empty. I'm probably missing something obvious. Would appreciate any pointers.
