Hello,
That’s a rather specialized behavior for the general purpose {% block %} tag.
I’m not convinced that building in such specialized behavior beats composing
blocks i.e. handling the condition with a {% if %} tag.
The Django template language has way too much ad-hoc, inconsistent syntax in
its built-in tags. I don’t like the idea of adding more.
We have to balance saving keystrokes against increasing the amount of things
every Django user needs to know. In this regard, adding that new syntax looks
like a bad tradeoff to me.
