than you won't like MPW very much!

I heartily second that!! I used Eiffel during one of my grad classes, and it
was wonderful.  The ability to imbed pre and post conditions, as well as
loop invariants, into your code is wonderfully useful as a debugging tool, and
as a way to define a classes interface.

Anyone out there want to do this?  Please??
