I'm trying to get a map out of a Goog events object (and also out of Domina events objects). Calling js->clj on either of these, even in the most recent version of cljs, doesn't seem to do anything; it just returns the inscrutable #<[object Object]> at the REPL. (It doesn't seem to produce maps o

Thank you both! That works. I'm not sure I understand why, though. From the error message, you would think it needs fewer steps of evaluation, not more. Meanwhile, if I do: (defn non-sandbox [func inputs] (map (fn [inp] (eval `(~func ~inp))) inputs)) this has no problem taking a function.
