title: Spyscope Java RuntimeException No reader function for tag spy/p
body: <p>I'm trying out <a href="https://github.com/dgrnbrg/spyscope" rel="nofollow noreferrer">spyscope</a>, and following the documented example, I'm getting:</p>
  
  <pre><code>user=&gt;  (take 20 (repeat #spy/d (+ 1 2 3)))
  
  RuntimeException No reader function for tag spy/d  clojure.lang.LispReader$CtorReader.readTagged (LispReader.java:1245)
  RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:221)
  RuntimeException Unmatched delimiter: )  clojure.lang.Util.runtimeException (Util.java:221)
  
  </code></pre>
  
  <p>My <code>~/.lein/profile.clj</code> is:</p>
  
  <pre><code>{:user {:dependencies [[spyscope "0.1.6"]]
          :injections [(require 'spyscope.core)
                       (use 'clojure.tools.trace)]
  
          :plugins [[lein-try "0.4.3"]]
          }
   }
  </code></pre>
  
  <p>My version of Leiningen is:</p>
  
  <pre><code>$ lein --version
  Leiningen 2.8.1 on Java 1.8.0_212 OpenJDK 64-Bit Server VM
  </code></pre>
  
  <p>I can't seem to find any answers on how to resolve this.</p>
