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.
