So, I can't jack into cider because leiningen is failing on repl startup. I'm pretty sure it's probably my code, but I can't isolate where the change is (it was working before). I'm wondering if someone can verify that is not lein and maybe give me some feedback on where to look for the issue. The error I'm getting is class clojure.lang.Cons cannot be cast to class java.lang.Comparable (clojure.lang.Cons is in unnamed module of loader 'app'; java.lang.Comparable is in module java.base of loader 'bootstrap')

never mind, I managed to isolate my code that was causing the error.

@dsouth the first thing I do in that sort of situation is remove the :init-ns config from project.clj, so I can use the repl require/reload to debug

usually I just end up permanently removing that config
