I am in strong disagreement with the inclusion of two appendices, as the net
effect will be an unfair evaluation of the issues by the user community.
Syntactic closures without a user interface will not be 'user friendly', but I
believe addresses the issues that are important. Extend-syntax has many nice
properties, but does NOT address the issues that are important to me. I can
not believe that a compromise is not attainable by the macro committee. I
implore the committee and other interested parties to resolve this divisive
To make the point totally clear I believe that R4RS should NOT be issued until
this issue is resolved with ONE decision.
