Dear cafe, I'm studying and enjoying for Haskell. I'm drawing some illustrations about lazy evaluation in Haskell. Of course, I know a lot of pretty good documents. My document is one of the starter-kits to them. Here is: Lazy evaluation illustrated for Haskellers http://takenobu-hs.github.io/downloads/haskell_lazy_evaluation.pdf https://github.com/takenobu-hs/lazy_evaluation If there are misunderstandings, please teach me. I'll correct them. I apology if my responses is late. This is my night work (fun) =) I wish you a happy new year. Enjoy, lazy!, Takenobu
