Comment (by Abhijeet Viswa):
I gave a shot at fixing this ticket. However, I got stuck real fast. F
expressions aren't resolved until the queryset is evaluated. However, the
test to check if the right-value is an instance of the forward relation's
class is performed during assignment. The only solution I could think of
is to defer the test for F expressions until queryset evaluation.
Maintainers, would this be the best approach?
