I've learned a few programming languages on my own. Bought this book to learn Haskell. I am on Chapter 2 and strongly leaning towards giving up. I can't learn from this book. Many examples have errors. Running examples and exercises in interpreter requires constant retyping of long lists and types, which is tedious and a waste of time. There are a lot of concepts that are either skipped completely or barely mentioned and I have to search for explanations elsewhere. There are no solutions to the exercises, so if I get stuck, I can't see how it is supposed to be done.

Typos and bad grammar everywhere. I've read reviews elsewhere that say there are technical inaccuracies (didn't get far enough to verify this myself). I would be disappointed even if the book was free. Look elsewhere for a good book to learn Haskell with, at least until another edition is released.

This book suffers some major flaws. First, I think someone new to Haskell (or not already familiar with a similar language) will really struggle with the pace of the material. So in that regards, its not really a "Beginning" book. Beginners will benefit far more from the book Learn You a Haskell for Great Good. Secondly, there isn't a single page that is without one or more: spelling errors, grammatical errors, or just plain awkward English sentences. This is really distracting, especially in technical books where language needs to be precise. It is obvious that English isn't the author's first language, so I can forgive him. However, the publisher should have put more effort into editing the manuscript before setting it to paper. By the shear quantity of mistakes, I suspect that they never even bothered reading it.

да не выходи ты больше уже

а можно как-то дешево cabal init без диалога просить делать шаблон для библиотеки, а не исполняемого файла?

cabal init --lib, наверно
