title: what does "ClassCastException java.lang.Character cannot be cast to clojure.lang.Named" mean?
body: <p>In a toy cascalog based project, I'm trying to use cascalog.more-taps because it contains some facilities to read and write to/from the filesystem.</p>
  
  <p>When loading my namespace I get this error message</p>
  
  <pre><code>user=&gt; (use 'playground.adult-dataset)
  
  ClassCastException java.lang.Character cannot be cast to clojure.lang.Named clojure.core/name (core.clj:1489)
  user=&gt; 
  </code></pre>
  
  <p>I see it's deep into clojure core, so before digging into it I was wondering if anyone knows anything about this.</p>
  
  <p>2 quick notes: </p>
  
  <p>cascalog.more-taps requires clojure 1.3.0 OR 1.4.0 while cascalog supports up to clojure 1.5.1</p>
  
  <p>The same error message showed up with Matchure, which is quite old and appears to be not maintained anymore.</p>
