That doesn't convince me yet. GC is just incorrect to use here.
D's GC like any other that is non-deterministic will hold on
to many external resources for longer than is feasible.

(Unique) ownership on the other hand isn't really what we are
looking at here, right? I mean, the DIP talks about what
happens when you are dealing with multiple references to
the same item.

That leaves us with RC, which I think is a good choice.
