Hi,

can we assume, that we have a graph without cycles, so that each node can be seen as the root of a sub graph?
Is it allowed, that a val in a trait is annotated with @ParentAccess? Or doesn't a val count as a method?

Kind regards,
Mario

No, the graph can contain cycles.

@ParentAccess on a val is not okay, since the structure may change.

Best,
Matthias

I think "with cycles" means that there is no Container which contains itself, is that true?
