I have been slowing workging my way through ST's "Haskell: The Craft ... " 2nd Ed. I have also been trying to do some of the exercises. For the most part this is no problem, but occasionally I get stuck and would like to see solutions. Are such available anywhere on the web? (I realize however that this book is used as a textbook, so perhaps not!). Basically, I am looking for what the 'right' answers are, esp when my answers are less then satisfactory. e.g. , I am in Ch 17 now, and cant find a very elegant solution to 17.2. (I will abstain from posting my solutions, but suffice it to say that I ended up using 'inits' for subsequences, and had to make the type Eq a => [a] -> [[a]] for sublists.
