Namespaces to the rescue: (ns your.name.space (:refer-clojure :exclude (first rest))) (defprotocol MySeq (first [this]) (rest [this])) (extend-protocol MySeq String (first [this] (.charAt this 0)) (rest [this] (subs this 1)) Object (first [this] (clojure.core/first this)) (rest [this] (clojure.core/rest this))) Now use first and rest as normal. Here some examples: your.name.space=> (first "abc") \a your.name.space=> (rest "abc") "bc" your.name.space=> (first [1 2 3]) 1 your.name.space=> (rest [1 2 3]) (2 3) Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
