Reddit mentions of Beginning Haskell: A Project-Based Approach

While LYAH is a fantastic book, I also felt a bit lost after reading it. You're still kinda useless as a Haskell programmer, all the practical things like 'drawing to the screen', 'calling a web API' are not included and bread & butter concepts like monad transformers, arrays/vectors, exceptions, any form of parallelism / concurrency, widely used language extensions etc., required to use/understand many libraries, are not discussed.

I can recommend Real World Haskell as a second book. Skip the basic early chapters and some of the outdated stuff, and you're still left with enough good parts. Also the Parallel and Concurrent Haskell book is truly excellent. It's written in a way that should make it accessible to someone with just LYAH under their belt. Both are available online for free, btw.

I haven't personally read it, but some people here recommend this book:

Also, have you seen this great collection:

http://dev.stephendiehl.com/hask/

? That should give you a good introduction to many of the advanced concepts.

I would also recommend to check out 24 days of hackage to get a good idea of Haskell's library ecosystem:

Hope that helps, good luck! ;-)

> I'm not aware of anything that covers ... lens in book form

Beginning haskell has an introduction to lens.

In addition, there are a few lens tutorials out there on the web; google for them.

Thompson's book was updated in 2011, and the Apress book looks like a good learning resource generally but I haven't read beyond a few chapters. There's a few odd typos where Mena writes "Platform does something" and he means GHC.

(Also, how about Bird's Pearls book? Hudak, School of Music?)
