Back when I did my degree, Haskell still wasn't a thing, like it was giving its first steps.

So the choice would be Lisp, Prolog, Caml Light, or the recently released Objective Caml.

The year before I took compilers design project, the TA responsible for it used to disallow them from the implementation language option list, as it would make the assignment too easy.
