clj-kondo success story: over the course of several months I managed to get from 1360 warnings and 179 errors to 72 warnings and 8 errors (yes, it's a large code base).
I found a good amount of dead code, made lots of small improvements/refactorings and found around 10 actual bugs.
[The remaining warnings are spurious and can't really be fixed without modifying clj-kondo]
If you write Clojure, I highly recommend clj-kondo.
Thank you @borkdude for all your work on this excellent tool! 🙏
