Found a more or less nice solution:
--8<---------------cut here---------------start------------->8---
(defn log [& more]
(.apply (.-log js/console) js/console
(into-array (map #(if (satisfies? cljs.core.ISeqable %)
(pr-str %)
%)
more))))
--8<---------------cut here---------------end--------------->8---
This prints all seqable objects using pr-str, all other objects are
passed directly to console.log. This way html elements are printed
clickable and most clojure data structures are printed in their native
representation.
