I have written some Haskell and I am quite certain, it is more practical for me to use Clojure. I know other people, who did compiler research (! see my points above about academic research) who rewrote the previous more or less exploratory Clojure solution in Haskell for better performance and other positive aspects. These are all good things. I also know about Facebook, Microsoft and other big companies using Haskell to great advantage. But the compiler e.g. is not something commercially applicable it is research, they don't have or want to sell it or make it a service. I also am not sure anybody would be interested to buy it, as they never told us about any practically applicable results (e.g. better parallelized HPC code) which was kind of the point of the research. I might be mistaken though. Anyway, the lecture and the exercises where rather good and even if it was the only thing that semester, it would justify the semester at the university for me.
