just to update the node for future googlers, this works great (needed 'elements' and not 'get' i think - it's what worked). but, here's what i have:

package Thing;

use Data::Dumper;

use Moose;

has 'search' => (
   is => 'rw',
   isa => 'HashRef',
);

has '_data' => (
   is => 'ro',
   isa => 'ArrayRef',
   traits => [ 'Array' ],
   default => sub { [] },
   handles => {
      _add_data => 'push',
      _get_data => 'elements',
   },
);

sub data {
   my ($self, $stuff, @err) = @_;
   if( $stuff and ref( $stuff ) eq 'ARRAY' ) {
      my $values = [ values %{ $self->search } ];
      foreach my $row ( @{ $stuff } ) {
         $self->_add_data( $row ) if( scalar( grep { $_ ~~ $values } v
+alues %{ $row } ) > 1 );
      }
   } else {
      return $self->_get_data;
   }
}
