Announcing `crem`

marcosh: > Nice! I’ll try to take a look at your work and see if I can make it compile for the whole project. The work I did got me like 99% of the whole module compiling. So, your work on an update is going to be really easy. I was about to submit a pull request but I hesitated because of that doctests literate Haskell part that confused me a bit. If you want, I can submit a pull request to get you most of the way there. Also, I didn’t quite get around to adding the upper boundaries back into the cabal file. So, without those, I imagine it could break pretty easily until you put those in (or a cabal freeze).
