Reevaluate difficulty levels of practice exercises
I think difficulty levels are a bit of a mess for this track right now. I try to keep evaluations in line with previous difficulty levels of existing exercises when I add new exercises, but I'm not happy about it.. At the moment not a single exercise has a difficulty higher than "Easy", which doesn't feel right to me. I want to adjust the difficulty ratings in the coming weeks in a separate PR.
Once the difficulty levels are improved I think it also would be good to order the exercises by difficulty level as discussed and suggested here: http://forum.exercism.org/t/are-go-practice-exercises-ordered/4464/11
Here are the median difficulty levels across the 66 tracks for each of the practice exercises emacs-lisp supports:
