This looks like a really good start. I like it.<p>My request is that you include some real case studies. That&#x27;s something that Peter Seibel did with his book, &quot;Practical Common Lisp,&quot; and it was terrific. I bought Seibel&#x27;s book--even though you could read it online for free--because he took the time to include those examples.<p>If you want to distinguish your book and encourage sales, show us how to do something that others have not. Build a game using a graphics library. (Real World Haskell just flirted with a GUI) Show us some web scraping or maybe build a stream editor. Make a server for the web. It doesn&#x27;t have to be Apache, but if it serves web pages, I&#x27;ll be impressed.<p>Anyway, I&#x27;ll be following your progress, but there are already good Intro to Haskell books. If you want to stand out, go the Seibel route and include a final part that has real programs that showcase Haskell as a viable alternative to python&#x2F;ruby&#x2F;java&#x2F;c&#x2F;c++&#x2F;etc...
