For situations like this, I find it handy to discover what reader-macros are expanding to. This works well: user=>(defmacro expand [arg] (println arg)) #'user/expand user=>(expand #(@%)) (fn* [p1__6536] ((clojure.core/deref p1__6536))) So it will have the same effect as (map deref agents), though the latter is clearer. I don't know why it's failing, but it seems unlikely that switching to (map deref agents) will fix it. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
