Wadler posted a blog entry the other day about a paper on pattern-matching
in Haskell (http://wadler.blogspot.com/). I've taken a first stab at turning
it into actual code for hackage (http://hpaste.org/13215). There are two
commented-out definitions that don't type-check, though, and the types are
too wild for me to grok. Anybody have any suggestions for 1.) How to fix it
and/or 2.) How to use data/type/newtype to simplify the types and make it
more manageable? Thanks!
