I wish more people looked past the unfamiliar syntax and understood why it exists and how it makes you achieve more with simpler code.</text><parent_chain></parent_chain></comment><story><title>Productivity brought by Clojure [slides]</title><url>https://www.slideshare.net/humorless/the-productivity-brought-by-clojure-149170292/</url></story>

There is a healthy choice of different editors and IDEs for Clojure right now, thanks to building on common foundations of &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;clojure&amp;#x2F;tools.nrepl&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;clojure&amp;#x2F;tools.nrepl&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Productivity brought by Clojure [slides]</title><url>https://www.slideshare.net/humorless/the-productivity-brought-by-clojure-149170292/</url></story>
