Once they know what polymorphism is, make them realize it is
sometimes useful, to write generic code, to be able to assume the
existence of certain operations on a polymorphic type variable. But
polymorphism doesn't allow this. Introduce functors as the way of
acheiving this, i.e. the way to abstract a type with particular
operations from a module implementation.
Best,
Daniel
