title: Is there some literal dictionary or array syntax in Objective-C?
body: <p>It's always been possible to create NSArrays (and NSDictionaries/NSNumber) with vararg method calls, like:</p>
  
  <pre><code>[NSArray arrayWithObjects: @"a", @"b", @"c", nil];
  </code></pre>
  
  <p>Can these be created with in-line literals in a new improvement to LLVM and Clang?</p>
