One thing I grew to really love is how small my changes were when I’m just adjusting a decidedly brownfield chain of functions that operate on data. With go in place at work, I added a couple fields to a core data type in my business and I ended up with thousands of lines of changes to pipe them everywhere. Doing the corresponding change in clojure would be <100 lines. I do miss the feeling I get with Haskell that if it type checks, I’m (maybe) good, but like Rich says “List[A] -> List[A] tells me almost nothing about the reverse function.”
