Hey Jason, You were exactly right (which is pretty impressive, being that you've never seen my code). In my (s/defn ..) form, there was an error that was failing silently.
(s/defn [one two] ... *#_(def params (atom '({}) ))* (def params '({})) (try (eval `(~afn ~@params)) (catch Exception e (println "Exception: " (.getMessage e))))) So the abouve code works. But if I instead use the commented version, I'll get an exception. It seems there's a problem passing in a form containing an atom to be dynamically eval'd. The error is mentioned on these posts ( here <http://clojure-log.n01se.net/date/2009-03-02.html> and here<http://www.raynes.me/logs/irc.freenode.net/clojure/2012-09-17.txt#>). Is there a way to pass in a form containing an atom to be dynamically eval'd? It's pretty important to my architecture, that all functions treat that system-atom the same. Any insights are welcome. *"java.lang.RuntimeException: Can't embed object in code, maybe print-dup not defined: clojure.lang.Atom@1c99db7 (NO_SOURCE_FILE:0)"* Thanks Tim Washington Interruptsoftware.com <http://interruptsoftware.com> On Fri, Jan 3, 2014 at 2:39 PM, Jason Wolfe <ja...@w01fe.com> wrote: > Thanks for the report. > > Schema fns inside of go blocks seem to work fine for me.
