I've uploaded my latest version to <http://hpaste.org/13263>. It
explicitly makes patterns polymorphic over the answer type of the case
statement by making Pattern a newtype and universally quantifying the
(un)currying and matching functions.

I'm not sure it makes sense to create a package just yet. At the very
least, you should ask Morten Rhiger first. The type signatures are
mine, but the code is mostly straight transcriptions from his paper.
