One thing that *must* be in Thing1 are ways to perform computation in the Scheme's native ring - and sufficient metadata to know what limits under which you are computing. Practically this means that (at least pieces of) the R6RS fixnum library should be mandatory for Thing1. david rush -- GPG Public key at http://cyber-rush.org/drr/gpg-public-key.txt _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
