I agree that having an incomplete set is not very nice, but for me the solution is to just forget about sets as fundamental types. The set articles are never really needed. In general anything expressed with them can be said more clearly without them, and half the time that they are used they're used wrong if taken seriously as sets. co'o mi'e xorxes _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
