This is an horrible solution, because of duplicate attributes:

YAML file:

tmpPages:
- Page:
   URL: http://www.perlmonks.org/

- Page:
   URL: http://www.perl.org/

Objects container:

package PagesGenerator;
our $VERSION=0.01;

use Moose; 
with 'MooseX::SimpleConfig';


use Page;


has 'tmpPages'=>(
              is=>'rw',
              isa=>'ArrayRef[HashRef]',
              default => sub { [ ] },
         );



has 'pages'=>(
              is=>'rw',
              isa=>'ArrayRef[Page]',
              default => sub { [ ] },
         );


sub BUILD{
    my $self=shift;
    

    
    @{$self->pages}= map {new Page(URL=>$$_{Page}{URL});} @{$self->tmp
+Pages};
    
    for ( @{ $self->pages } ) {
        print $_->URL;
        print "\n";

    }
    

}

Any other idea?
