When you look for a generic "null" or "void" object, that is used for a particular library, then any unique value is sufficient, whether immediate or not. As I already replied to Graham, immediacy vs. non-immediacy is an implementation detail and shouldn't concern us here. The performance benefit is negligible. I have the feeling that immediacy is desired by the proponents of a new unique "void" value because it *feels* right to them, not because there is any real requirement. cheers, felix _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
