Have you looked at OOHaskell?

With the exception of pure-functional objects and binary methods, I
think we have considered almost every OO pattern/idiom we could find,
including nominal/structural subtyping, co- and contra-variance,
self-typing, etc. The DARCS repository contains the complete code for
all of the examples and patterns. To clarify, the point of OOHaskell
is to use Haskell as a tool, laboratory bench, for exploring various
(thorny) OO issues.
