title: Fast Enumeration With enumeratorAtPath?
body: <p>Are there any issues I may be missing using fastEnumeration with the enumerator below? I only ask as code examples (online &amp; books) always seem to use a whileLoop. The code sniped works fine, just  curious if I am missing a potential issue. Please not this is just a test with no error checking.</p>
  
  <pre><code>NSDirectoryEnumerator *dirEnum;
  NSString *eachPath;
  
  dirEnum = [fileManager enumeratorAtPath:sourceDir];
  for(eachPath in dirEnum) NSLog(@"FILE: %@", eachPath);
  </code></pre>
