(As you pointed out, I can't use edn/read-string because it doesn't support regexes). So what's wrong with this?: (defn safe-read-string [s] (binding [*read-eval* false] (read-string s))) Does the text at the link below answer that question? I know it isn't exactly short, but hopefully it eventually gets to the point: htt <http://clojuredocs.org/clojure_core/clojure.core/read> p://clojuredocs.org/clojure_core/clojure.core/read<http://clojuredocs.org/clojure_core/clojure.core/read> If it doesn't answer your question, I'd like to know what question you still have afterwards so I can update the explanation there. You know, make it longer so even fewer people will read it :-) Andy -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
