Today I'm going to #rant about #haskell libraries. I'm a Haskell supporter, I think it's a great language, but that doesn't mean it doesn't have problems. Some of them are surprising and I want to talk about them. At the end of the rant I will have tips for developers using Haskell and for libraries developers (in any language, some rules are universal) so bear with me. It's a long rant but there is a good ending ;).
