Since we're discussing the semantics of LETREC, I've always thought it was a wart in the language to specify LETREC in terms of SET! It would be nice if implementations were permitted (but not required) to implement LETREC in terms of a fixed-point operator as an alternative to SET!
One advantage of this is that it would be much easier to create a purely functional subset of Scheme. -- ~jrm _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
