I think the tree tag for recursing data structures where the children have the same structure as the parent nodes is pretty useful.
{% tree item in menu %}
{% if treeloop.first %}<ul>{% endif %}
<li>
<a href="{{ item.url }}">{{ item.name }}</a>
{% subtree item.children %}
</li>
{% if treeloop.last %}</ul>{% endif %}
{% endtree %}Just like a {% for %} loop, you can access the key of each list item:
{% tree key, item in menu %}
<li>
<b>Item {{ key }}</b>: {{ item.name }}
{% subtree item.children %}
</li>
{% endtree %}Since Twig 4 is under development, would you consider adding this extension to the Twig core?

I can clean up the documentation and such a bit if that helps. I didn't write the original or even the first set of tweaks, but I did get it working with Twig 3 and the dev version of Twig 4.
