If you need to keep the "canonical list" around, then sort them and then keep the sorted result around (i.e. cache the sorted list). This way, you could avoid the "factoradic index". -- Dieter _______________________________________________ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
