from Anssi [https://groups.google.com/d/topic/django-
developers/FojuU0syO8Y/discussion on django-developers]:

You can annotate raw SQL with expressions. I think the only case that
can't be done with expressions is addition of extra tables to the query. I
am certain we will get a solution to this too in future releases.
