Shouldn't that be the job of the run-manager?
What's saying that the current design is correct? I'm not saying it's
incorrect, I don't know it enough to be the judge of that, but there
might be a slim chance that it is.
I still think that the just_after belongs in the layout class, not the
run class. Yes it would require a rewrite of some stuff, a shift of
paradigm regarding handling of the runs, and it can possibly be wasted,
maybe even break badly, but the runs position relative another run isn't
the business of a run IMHO. Maybe even more since runs participate in
relationships with both layout a line.
I might be wrong, but until I'm convinced that the current way is the
best of the possible ways to do it it's still my opinion.
Maybe it's because the runs are so data centric that we tend to think of
them in data centric terms, when we perhaps should think of their
behaviour.
Then again, I might be way off again...
