If the term "general" is still used in R7RS to refer to a /proper subset/ of the complex numbers (haven't done a search), I would say that this is a confusing usage and should probably be changed. To most people, "general" does not mean a proper subset. _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
