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.

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.
