Thomas Lord scripsit: > 2a) sequence predicates should not be primitive in Scheme
Such was the case until R4RS. In RRRS and R3RS, the two-argument version was standardized, and it was documented that some implementations allowed more than two arguments. The language about monotonic sequences goes back to RRRS. (I can't find a usable copy of RRS on line; RS is silent on the subject.) -- John Cowan <[EMAIL PROTECTED]> http://ccil.org/~cowan Micropayment advocates mistakenly believe that efficient allocation of resources is the purpose of markets. Efficiency is a byproduct of market systems, not their goal. The reasons markets work are not because users have embraced efficiency but because markets are the best place to allow users to maximize their preferences, and very often their preferences are not for conservation of cheap resources. --Clay Shirkey _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
