Using Moose::Meta::Attribute::Native::Trait::Array lets you write code like... 
package Thing;

use Moose;

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

package main;

use Data::Dump;

my $thing = Thing->new;

$thing->add_data({$_ => $_**2 })
    for 1..5;

dd $thing->get_data(2);
dd $thing;

__END__

{ 3 => 9 }
bless({
  _data => [{ 1 => 1 }, { 2 => 4 }, { 3 => 9 }, { 4 => 16 }, { 5 => 25
+ }],
}, "Thing")
