That should be possible with a macro. For example, I use this: https://bitbucket.org/kumarshantanu/clj-miscutil/src/acfb97c662d9/src/main/clj/org/bituf/clj_miscutil.clj#cl-1009 Maybe you need something like this(?): (defmacro verify-my-arg "Like assert, except for the following differences: 1. does not check for *assert* flag 2. throws IllegalArgumentException" [err-msg arg] `(if ~arg true (throw (IllegalArgumentException. ~err-msg)))) Then use it thus: (defn foo [m] {:pre [(verify-my-arg "m must be a map" (map? m))]} (println m)) Regards, Shantanu -- You received this message because you are subscribed to the Google Groups "Clojure" group.
