+1 for this, before I test if someone already knows the answer, is it
possible to use this var in blocktrans?
{% url args as myurl %}
{% blocktrans %}
foo <a href="{{ myurl }}">baz</a>
{% endblocktrans %}
That's potentially the best solution for the endless discussion about
urls in blocktrans.
Best,
David
