Comment:
Thanks for this ticket, however `RawQuerySet` doesn't implement all
methods you can use with `QuerySet` and is not intended to do this. We
cannot mirror `QuerySet.count()` because there is no
annotation/aggregation mechanism in `RawQuerySet` and wrapping a raw SQL
(suggested in stack overflow) can be clunky. You can start a discussion on
DevelopersMailingList if you don't agree.

No, these are different classes.
