That would be the safe thing, yes, but R7RS does not explicitly require either safety or unsafety. I would not want to standardize anything that can't be made safe, but an unsafe implementation that can only be used in limited ways (viz. you are not allowed to gc the source vector until the destination vector is fully initialized) isn't necessarily unusable. -- John Cowan http://www.ccil.org/~cowan [email protected] At the end of the Metatarsal Age, the dinosaurs abruptly vanished. The theory that a single catastrophic event may have been responsible has been strengthened by the recent discovery of a worldwide layer of whipped cream marking the Creosote-Tutelary boundary. --Science Made Stupid _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
