It sounds like you're looking for refer-clojure: https://clojuredocs.org/clojure.core/refer-clojure
E.g., for your project: (ns mw.mwm (:require [clojure.pprint :as pp] [clojure.walk :as walk]) (:refer-clojure :exclude [defn]) (:gen-class)) Tested in a fork: https://github.com/mattiasw2/cdn77-purge/compare/renamed_to_defn...benizi:fix-defn-issue Defining your own `defn` is a fairly unorthodox thing to do. (Usually it's less Clojure-centric names that cause problems, like `time` from the example, or `filter`, `min`, or `max`.) Based on your comment <https://github.com/mattiasw2/cdn77-purge/blob/ee259d6dee23c732067b80df57a4f5f064eacd0b/src/mw/mwm.clj#L44-L46>, it seems easier to just write a different version of `get` that handles nils the way you want, instead of complicated macro behavior. E.g.: (defn get! ;; "!" seems better than "?" to indicate the "dangerous" assert "Get a value out of a map, asserting it is non-nil" [from key] (let [val (get from key)] (assert (some? val) (str key " is nil")) val)) Seems much more straightforward than a macro that translates (:key? map) to something roughly equivalent to (get! map :key).
