=head1 NAME
MooseX::Storage::Engine::Trait::DisableCycleDetection - A custom trait to bypass cycle detection
=head1 SYNOPSIS
package Double;
use Moose;
use MooseX::Storage;
with Storage( traits => ['DisableCycleDetection'] );
has 'x' => ( is => 'rw', isa => 'HashRef' );
has 'y' => ( is => 'rw', isa => 'HashRef' );
my $ref = {};
my $double = Double->new( 'x' => $ref, 'y' => $ref );
$double->pack;
=head1 DESCRIPTION
C<MooseX::Storage> implements a primitive check for circular references.
This check also triggers on simple cases as shown in the Synopsis.
Providing the C<DisableCycleDetection> traits disables checks for any cyclical
references, so if you know what you are doing, you can bypass this check.
This trait is applied to an instance of L<MooseX::Storage::Engine>, for the
user-visible version shown in the SYNOPSIS, see L<MooseX::Storage::Traits::DisableCycleDetection>
