    My Magic: the Gathering implementation uses a few GADTs. Interestingly they use GADTs in very different ways. Source code is here: https://github.com/MedeaMelana/Magic/blob/master/…

    You don't really need to understand all these things in order to build "real" things with it. Just build something without caring too much whether an experienced Haskell programmer…

    Not really. There's a really nice paper by Graham Hutton, "A tutorial on the universality and expressiveness of fold" which goes into a bit more depth than OP does. Your question i…

    Can you tell us more about the book? Would you recommend it? Is it easily accessible?
