+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' );

+
+=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>

+MooseX::Storage::Engine::Trait::OnlyWhenBuilt - An engine trait to bypass serialization
+
+=head1 SYNOPSIS

+    {   package Point;

+        use MooseX::Storage;
+
+        with Storage( traits => [qw|OnlyWhenBuilt|] );

+
+    # the result of ->pack will contain:
+    # { x => 4, z => 3 }
+    $p->pack;
+
+=head1 DESCRIPTION
+
+Sometimes you don't want a particular attribute to be part of the
+serialization if it has not been built yet. If you invoke C<Storage()>
+as outlined in the C<Synopsis>, only attributes that have been built
+(ie, where the predicate returns 'true') will be serialized.
+This avoids any potentially expensive computations.
+
+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::OnlyWhenBuilt>
