Let's build an implementation of djb's redo from scratch in Haskell. In this, the first episode, I'll explain what the purpose of the program is, write some initial code, and create a GitHub repository for you to follow along with if you want. Just to clarify, the book I was writing is the basis for this video series. I don't plan to publish the book because I think the material is better served by videos. However, maybe there will be a different book in the future...
