XHaskell is certainly related work, and we discuss the relation in our
paper. The short story is that HaRP is much more lightweight, it is
basically just syntactic sugar for parser combinators performing
regular pattern matching over a list, with some clever semantics for
the patterns involved. It has, for better or worse, none of the
intricate type-based machinery that is XHaskell's claim to fame.
