Only if they were using polymorphic data structures. But most of the Real
World uses null-terminated data structures instead, despite that approach's
practical disadvantages, so students need to learn how to work with them too --
and CS2 seems like an appropriate place to do that. So yes, they WOULD have a
conditional for the outer part.
