(facetious) Whenever someone tries to create a username that happens to conflict with a pre-existing attribute, just tell them that username is already taken. Just watch out when your user HasOwnProperty tries to delete his account. (/facetious) Namespaces are great, we should have lots of them. But be very careful about reusing one without checking to see if it's already inhabited. When a language design does this sort of thing, it tends to make us skittish about continuing use of said language. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list
