Yes, sure. The object doesn't care about the meaning of that number. But (as also Henrik pointed out), this looks very much like a +Link or +Joint relation, doesn't it? Storing the id of some other object sounds like a lot of maintenance work, to keep it everything consistent. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
