title: Logging in Clojure
body: <p>For Java development, I use Slf4j and Logback.</p>
  
  <pre><code>Logger logger = LoggerFactory.getLogger(HelloWorld.class);
  logger.debug("Hello world.");
  </code></pre>
  
  <p>How to use these two libs in Clojure programs? Majority of Clojure programming doesn't has .class concept (possible of course via AOT).</p>
  
  <p>What do you use for logging in Clojure?</p>
