Swift does away with pointers == pervasive ARC

Swift targets the same VM as ObjC so I think ARC was a foregone
conclusion.  And for that case it makes sense, as predictable
performance is crucial on mobile platforms.  Since D has raw
pointers and inline assembly I don't see ARC as being terribly
practical here however.  It's kind of the same issue as having
write barriers to support an incremental GC.
