Great work! But unfortunately it seems that after last languages update, the Clojure solutions of the "Power of Thor - Episode 1" puzzle are not accepted by the automatic grader any more. Neither the practice, nor the Code Golf solutions are accepted. I tried some mine and then some of other published solutions, and none of them passed the grader Actually, I discovered that sometimes some tests are accepted, but when the same test is rerun, then it got rejected again. The grader just times out. I have just tested "Don't Panic" puzzle, and it has the same problem.
