Re: potential bug with pr-str+print

One more risk of (print ...), for debugging, is that it pollutes the results of functions that use (with-out-str ...). Consider using clojure.tools.logging instead. Setting it up takes some brainpower, but the investment is well worth while. -- You received this message because you are
