Goto is often the cleanest way to jump to error handling at the end of a function. I always smile at contorted efforts to avoid goto at any cost. Recently I saw something like this:

  do {
    /* deeply nested code */ 
    if (error) {
      break;
    }
  } while (0);

  /* error handling */

And no, it was not the do/while macro trick. It was advertised as structured programming.
