title: Switch statement syntax for same action through different cases
body: <p>Two constants (1+2) share the same case statement. I don´t want to double the code. </p>
  
  <p>What is the right syntax to do this?</p>
  
  <pre><code>switch (expression) {
          case 0:
              [self taskA];
              break;
          case 1:
              [self taskB];
              break;
          case 2:
              [self taskB]
              break;
          default:
              break;
      }
  </code></pre>
