While I'd prefer that approach myself, the way Bruce is proposing does
have a definite advantage: there is no problem with confusion between
global users and database-local users of the same username. "foo@" is
global, "foo" is not.
My own feeling is that the confusion argument is a weak one, and that
not having to use "@" to log in as a global user would be worth having
to avoid duplicating global and local names. But I'm not sufficiently
excited about it to volunteer to do the work ;-)
