Comment (by akaariai):
True, that example isn't valid Python.
The simplest example is something like this:
{{{
.filter(unter__id=1, id=F('unter__id'))
}}}
where unter is any reverse relation.
Depending on the ordering of the kwargs dict the F() either creates a new
join or not. This means the same query will execute differently on
different runs if dict randomization is turned on.
