| The Comparison operators: <code class="computeroutput"><span class="special">==</span></code>, |
| <code class="computeroutput"><span class="special">!=</span></code>, <code class="computeroutput"><span class="special"><</span></code>, |
| <code class="computeroutput"><span class="special"><=</span></code>, <code class="computeroutput"><span class="special">>=</span></code> |
| and <code class="computeroutput"><span class="special">>=</span></code> work generically |
| on all Fusion sequences. Comparison operators are "short- circuited": |
| elementary comparisons start from the first elements and are performed |
| only until the result is clear. |
