How is this different in actual use from just leaving them undefined? The point of feature groups is to be able to *introspect* on what your chosen Scheme can and can't do. -- 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
