Recently, I've been in a mood to play with ORMs in Haskell. The most recognizable one is Persistent, developed as part of a Yesod project. It is quite pleasant to work with, I must say, but some assumptions it makes are... not suitable for me. So I've looked for something different and I found out about Groundhog, yet another ORM in Haskell. Unfortunately, it is almost identical to Persistent, but maybe instead of searching for the perfect library, I will be able to adapt it to my needs?
