`case` doesn't match quoted symbols

Defect Major Resolved Completed Unassigned Shantanu Kumar bug Fri, 7 Sep 2012 12:28:50 -0500 Fri, 7 Sep 2012 16:49:37 -0500 Fri, 7 Sep 2012 16:49:37 -0500 0 0 <p>This did reveal a bug though the ticket description does have a user error. The tests for case can only be literals - you should not quote the test values. For example the following is how symbols should be tested:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">(let [a '&amp;] (<span class="code-keyword">case</span> a nil :nil &amp; :amp :none))</pre> </div></div> <p>The above code that quotes the test is actually equivalent to:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">(let [a '&amp;] (<span class="code-keyword">case</span> a nil :nil (quote &amp;) :amp :none))</pre> </div></div> <p>Which happens to work but probably isn't intended.</p> <p>With the coming patch CLJS now works as Clojure.</p> <p>Fixed, <a href="http://github.com/clojure/clojurescript/commit/c8e301a9b058f81bb599026a07f97ccdf4441730">http://github.com/clojure/clojurescript/commit/c8e301a9b058f81bb599026a07f97ccdf4441730</a></p> Global Rank
