Will they have had exposure to more "traditional" OO programming?  If
so, it might be useful to note the difference between Haskell type
classes and C++/Java/whatever classes, namely that Haskell decouples
types and the interfaces that they support.  The advantage is that you
can extend a type with a new interface at any point, not just when you
define the type.
