&#x27;Lack&#x27; of frameworks. I always think it&#x27;s kind of funny when starting a new Clojure web project, I have to explicitly insert a middleware for parsing parameter strings into a Clojure data structure, and then another middleware for transforming the string keys in that structure into keywords. There are just a bunch of things that don&#x27;t magically work for you. That said, I really enjoy Clojure and appreciate&#x2F;understand the high configurability.
