I don’t generally use records or protocols in my Clojure code so the fact that Clojure compiler doesn’t seem to detect changes in the function bodies of either took me by surprise recently. Googling turned up this issue for Leiningen. Reading through the issue I ended up specifying all the namespaces containing these structures in the :aot definition in the lein project.clj. This meant that the namespace was re-compiled every time but that seemed the lesser of two evils compared to the clean and build approach.
Where this issue really stung was in the method-like function specifications in the records and as usual it felt that structure and behaviour was getting muddled up again when ideally you want to keep them separate.
