"Real World Haskell? Isn't that an oxymoron?" I heard the question asked in one way or another many times as I lugged the book between meetings (looking for spare minutes to read it). As the authors explained in my Real World Haskell interview, Functional Programming languages generally and Haskell specifically, might have once be confined to the ivory tower but no longer. And this book is one great way to help bring the benefits of haskell to your coding projects.
I'm still not sold on Static vs. Dynamic Typing, and Ruby remains my language of choice, but I've got to say that Haskell is not nearly as intimidating as it once was. Maybe with enough intentional use it will be a tool I reach for more often without having to think about it.
Real World Haskell is a big, solid book with a lot to commend it. It's well organized, easy to read, and loaded with good examples. Best of all, it's written by long-term members of the Haskell community, so you're getting idiomatic code and well reasoned explanations by guys who have been there. The only down side is a somewhat weak index.
If you're a rubyist looking to understand more about Haskell or Functional Programming in general, this is the book for you. In fact, if you're a rubyist, you should be looking at this kind of book in general. I can't wait to see RWH reading groups start up within Ruby Brigades ... it will certainly make us better programmers.
