I'd try to separate the "I/O or side-effecting" parts from the "purely data processing" parts. This makes the program much easier to test --- the "purer" the code, the better it is. This also helps tease apart domain-agnostic parts from domain-specialised parts, which is useful, because

Hey James, Another small suggestion is you can just pass println to map, since it takes 1 argument in your case. (map println (sort builds)) But here, since you just want to perform side effects, maybe run! would be a better function to use. (run! println (sort builds)) This would cause it to
