Rather than use `str`, try using `pr-str` to get a more accurate
representation of the data:
(pr-str nil)
= nil

Hello, Clojure users.
I'm a beginner of Clojure, so it could be a dumb question.
I'm playing with Apache Storm, and I leave below line to see tuple value
when something is wrong.
(log-warn Can't transfer tuple - task value is null. tuple type: (type
tuple) and information: tuple)
log-warn is defined...
(ns backtype.storm.log
(:require [clojure.tools [logging :as log]]))
(defmacro log-warn
[ args]
`(log/warn (str ~@args)))
But it prints like...
2015-04-23T14:46:59.517+0200 b.s.d.worker [WARN] Can't transfer tuple - task
value is null. tuple type: and information:
Evaluated value of (type tuple) and tuple value (maybe toString()?) doesn't
printed.
Is this possible? If possible, please let me know what type the tuple can be.
Thanks!
Regards.
