title: Commenting try catch statements
body: <p>What is the proper place to explain error handling in a try-catch statement?  It seems like you could put explanatory comments at either the beginning of the try block or the catch block.  </p>
  
  <pre><code>// Possible comment location 1
  try
  {   
      // real code
  }
  // Possible comment location 2
  catch
  {
      // Possible comment location 3
  
      // Error handling code
  
  }
  </code></pre>
