In R6RS, you can write a portable reflective equality predicate that descends through records. In R7RS-small you cannot, because there are no record inspection procedures. In both cases, both immutable and mutable records are considered to have identity. -- John Cowan [email protected] http://www.ccil.org/~cowan C'est la` pourtant que se livre le sens du dire, de ce que, s'y conjuguant le nyania qui bruit des sexes en compagnie, il supplee a ce qu'entre eux, de rapport nyait pas. --Jacques Lacan, "L'Etourdit" _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
