You'd have to subclass list to be able to do something with "reference-slices". Probably returning a special object from __getslice__ which itself has references back to the original list and implements any changes back in the original instead of in itself. I haven't tried to imagine if this is even feasible. Anything "indexing" with : in it is a slice, so a copy, while anything with only a single index as you have in l[-1] is just a reference to one element in the list. -Peter -- http://mail.python.org/mailman/listinfo/python-list
