Independently from my decision to revisit Haskell, some colleagues here have just started a discussion group to learn the language. I hope I'll have time: I enjoyed my brief dalliance with it in 2003.
One of my Dublin colleagues has a copy of Thompson’s book, Haskell: The Craft of Functional Programming so I'll steal that when I return, and astound my friends with my new-found Haskell brilliance.
I'd recommend Graham Hutton’s new book if you can get hold of a copy. It’s clear, well written, concise, and you might find the examples more interesting…

No, but I've recommended it often enough that I might have to start demanding commision :-).
