Actually I'm being overly complicated here as with dynamic arrays I can simply do,

         immutable(Node) idup() pure const @property
         {
               return immutable(Node)(id, links.idup);
         }

... so the real issue here seems to be that there's no canonical way (that I can 
find) to idup an _associative_ array.
