I don't think so -- I suspect that this macro is as simple as   (define-syntax set     (syntax-rules ()       [(set where what)        (namespace-set-variable-value! where what)])) which is even simpler than that:   (define set namespace-set-variable-value!) -- </blockquote> I appreciate the help but your suggestions kind of defeat my purposes. First, I'm trying to stick with standard scheme.  Second, I'm trying to get a handle on syntax-case.  A solution to my unmolested and unqualified problem would be a big help and greatly appreciated. </body> </html>
