BTW, I am a happy customer of FP Complete. I have bought four Haskell books in the past, but Haskell has never really clicked for me (but studying Haskell has helped using Clojure). Whenever I get some free time I use your IDE and online lessons. My hope is that by the time my one year subscription is up, that I will be comfortable sometimes using Haskell instead of Clojure or Java on large projects.
