  package Point;
  use Moose;
  use MooseX::Storage;

  with Storage('format' => 'JSON');

  has 'x' => (is => 'rw', isa => 'Int');
  has 'y' => (is => 'rw', isa => 'Int');

  1;

  my $p = Point->new(x => 10, y => 10);

  ## methods to freeze/thaw into
  ## a specified serialization format
  ## (in this case JSON)

  # pack the class into a JSON string
  $p->freeze(); # { "__CLASS__" : "Point", "x" : 10, "y" : 10 }

  # unpack the JSON string into a class
  my $p2 = Point->thaw('{ "__CLASS__" : "Point", "x" : 10, "y" : 10 }');
