First, {% else %} is supported, so your example can be written as:
{% ifequal a 1 %}blah{% else %}foo{% endifequal %}
If you want some more advanced tags in your templates, you might want to
look at the template-utils: http://code.google.com/p/django-template-utils/.
I think some of its features, like getting objects from a model, do not
belong in a template language, but the {% if_greater %} tag can be very
useful. I use it when I want to display a number below a certain value in
red for example.
