Example:

for (;;) {

/* Quite a bit of code to find the next candidate */
if (no more candidates) break;

/* Check if this candidate can be ignored */
if (candidate can be ignored) continue;

/* Do the real work */
do_some_work ();
}

You can easily change this into "structured" code, but it doesn't
improve it.
