Haskell for non-Haskell's sake

[Manuel M T Chakravarty]

Graham's post reminded me.  We have been using a 1000 LOC
Haskell program to automatically test and grade two
assignments in a course on Distributed Systems (where
assignments are implemented in C and Erlang).  The testing
program is, in fact, general purpose in that it implements
an EDSL for marking programming assignments.
