By the way, what concrete benefits do you think lazy evaluation offers in contrast to lazy data structures? I've noticed that with Clojure I can enjoy most laziness just the way I want to enjoy it by using lazy sequences and data structures. There's no lazy evaluation but I haven't really bumped into any problems with eager evaluation in Clojure. But Haskell goes deeper and has lazy evaluation as well. What additional, further good does it bring? (Besides nearly impossible debug prints...)
