Now that someone has got the "you shouldn't do that" speech out the way,
here's how you can actually achieve it. Install the 'smart if' tag[1]
from djangosnippets, and alter your template code like so:

{% for u in users %}
 {% if u in superu %}
   {{ some_content }}
 {% endif %}
{% endfor %}

The smart if tag is allegedly slated for inclusion in django 1.2.

Cheers
