After being corrected about missing the construction of a None-containing list, one needs of course to think about the waste of resources, as a possible result-list is created in any case. I personally still don't mind that (if we talk about a few hundred objects a top) - but it makes a strong point against a general usage. Diez -- http://mail.python.org/mailman/listinfo/python-list
