I'm guessing i don't totally understand how getters / setters work because I just can't figure out how to get this to work:

Thing.pm

package Thing;

use Data::Dumper;

use Moose;

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

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

sub data {
   my ($self) = shift;
   if( @_ ) {
      my $stuff = shift;
      my $values = [ values %{ $self->search } ];
      foreach my $row ( @{ $stuff } ) {
print Dumper [ $row ];
print @{ $self->_get_data }, "\n";
print $row, "\n";
         $self->_add_data( push @{ $self->_get_data }, $row ) if( scal
+ar( grep { $_ ~~ $values } values %{ $row } ) > 1 );
      }
   } else {
      return $self->_get_data;
   }
}

1;

$VAR1 = [

$VAR1 = [
          {
            'blah' => 'barf',
            'other' => 'four',
            'thing' => 'two'
          },
          {
            'blah' => 'one',
            'of' => 'something',
            'other' => 'four',

            'bl' => 'another'
          }
        ];

So, if I do $thing->data( [{ 'one' => 'thing', 'to' => 'use', 'another one' => 'one', 'two' => 'two' }, { 'another' => 'thing', 'to' => 'push', 'and => 'so on', 'just to make => 'one, 'this valid' => 'two' }] ); it adds each valid hash to _data.
