Apparently twig defines some loop variables inside the for-loop:

{% for v in a %}
    {% if loop.index0 is even %}
        ...
    {% endif %}
{% endfor %}

If you use it for styling you can do:

{% for v in a %} 
  <div class="link {{ cycle(['even', 'odd'], loop.index0) }}">
  </div>
{% endfor %}
