BTW I teach a "programming languages" course which includes an introduction to Haskell and an introduction to parsing and compiling. The students modify an interpreter that I wrote. The complete Haskell source for the language (simple block structured imperative language with a single integer daya type) is only 600 lines, of which about half is the parser. This compares favourably with a similar toy compiler in C++ that was used before I took over the course --- it ran to well over 5000 lines!
That's very interesting to me, since I, too, teach a programming languages course which includes an intro to Haskell and to parsing. An interpreter for an imperative language would pull a lot of topics nicely together. Do your students know any Haskell coming into the course, or is your introduction to Haskell their first taste of it? Does the imperative language include procedures? With what methods of binding arguments to parameters? What sort of modifications can the students manage?
