That requires all implementations of define-record-type to allow introspection on records, which the current SRFI 9 does not. A procedural layer like that of R6RS or (better) SRFI 99 needs such a thing, but pure syntactic records don't, only a mark bit to say they are not vectors and a uid that the predicate checks for. -- John Cowan [email protected] http://ccil.org/~cowan If a traveler were informed that such a man [as Lord John Russell] was leader of the House of Commons, he may well begin to comprehend how the Egyptians worshiped an insect. --Benjamin Disraeli _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
