Define "builtin". It was pointed out recently how one could derive a "Set" class from a Disjunction type, implementing the few things that Sets can do that Disjunctions can't. Put this in a module, and a simple "use Set" at the start of your script is all that would be needed to have full Set functionality. ===== Jonathan "Dataweaver" Lang __________________________________ Do you Yahoo!?
