Dave Thomas (from The Pragmatic Programmers, not from Wendy's :)) has announced an Erlang book (http://www.pragmaticprogrammer.com/titles/jaerlang/) in the Ruby mailing list. A few responses showed an interest in a similar book for Haskell. You can see the thread here: http://tinyurl.com/2ecpsn. Dave answered such requests by saying: "I'd love to do one. It's a question of finding the right author.". If you think this would be up your alley, perhaps you could contact Dave in regards to this matter. Just a heads up, from a potential reader. :) Regards, Antonio -- http://antoniocangiano.com Zen and the Art of Ruby Programming
