I learned some haskell as my hobby language a few years back. It was very cool and forced me to think about programming differently (and finally grok recursion). It never felt like a good language for data analysis to me though (maybe that's cause this library wasn't around? lol). This isn't meant a criticism of this library, instead, I'm curious the use cases the author, if you're around or a user, has in mind. Congrats on the v1 release!
