In the tag code, test to see if context['forloop']['first'] is True or
not. That's the Python equivalent of {% if forloop.first %} in a
template.
But, seriously, use {% if forloop.first %}. It even works for nested
for-loops:
{% for x1 in some_list %}
{% for x2 in some_other_list %}
{% if forloop.parentloop.first %}
x1 is still on it's first iteration.
{% endif %}
{% endfor %}
{% endfor %}
"parentloop" always points to the parent loop or is {} when there's no
nesting above the current loop.
(And, yes, the wheels will come fall off if you ever create your own
context variable called "forloop", so don't do that.)
