I appreciate the advice, but forloop.first won't work for what I'm
trying to do. If the first thing chosen is in the second iteration of
the for loop, then forloop.first is never true. I don't want to know if
I'm on the first iteration of the loop. I want to know if it's the
first time in the if clause:
{% for thing in mylist %}
{% if thing.test %}
{% iffirst %}Things: {% else %}, {% endiffirst %}
{{thing}}
{% endif %}
{% endfor %}
