I don't think this is a great idea: this will change the semantics of code using call-with-values, will be less efficient, and may throw errors in some cases - R5RS (in contrast to CL and R6RS) does not automatically adjust the number of result values to the number of values expected by the location where the result(s) is/are used. cheers, felix _______________________________________________ Chicken-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/chicken-users
