And yet, we have APL, which doesn't give a fig about type.  If Ada is a 
fascist, APL is a hippie.   Yet, somehow, useful work gets done with it.

I think the type thing is overblown.  However, the ability to create 
abstract types can be very useful, particularly if relations and 
operations on mixed-type expressions can be exhaustively defined.

Of course, used incorrectly, it's just another set of bugs.
