one particular thing that we still lack is something like book "Haskell in real world"
How about: http://www.amazon.co.uk/Applications-Functional-Programming-Colin-Runciman/dp/1857283775/sr=1-16/qid=1166024994/ref=sr_1_16/202-8679714-4706263?ie=UTF8&s=books Applications of Functional Programming (Hardcover) by Colin Runciman (Editor), David Wakeling (Editor) Routledge, 1995. Synopsis This book is unique in showcasing real non-trivial applications of functional programming using the Haskell language. It presents state-of-the-art work from the FLARE project and will be an invaluable resource for advanced study, research and implementation. The applications covered in the book range from workforce management and graphical design to computational fluid dynamics. Regards, Malcolm
