well yes, but you have to admit that
{% for name, description in list %}
{{ name }} - {{ description }}
{% endfor %}
looks way better ;)
just some syntax sugar, but I think it's actually useful

+0 - I like this feature, but I didn't know when I first looked at it
whether its a zip() or concatenation, that should be clear

well, I can see a use case for this - if you want to iterate over
multiple lists at a time... for example if you want to render
something to columns rather that rows in a table, that's a change that
shouldn't require a change to the view function, yet it is near
impossible to achieve withou custom filters or tags...
