=head1 NAME
DBIx::Class::Ordered - Modify the position of objects in an ordered list.
Returns an B<ordered> resultset of all other objects in the same
group excluding the one you called it on.
+Underneath calls L<DBIx::Class::ResultSet/search>, and therefore returns
+objects by implicitly invoking L<C<< ->all() >>|DBIx::Class::ResultSet/all>
+in list context.
+
The ordering is a backwards-compatibility artifact - if you need
a resultset with no ordering applied use C<_siblings>
