I just checked and the following Scheme implementations can not handle macro-forms that are dotted lists: Gambit-C 3.0 (define-macro) MzScheme 103 (define-macro + syntax-rules) Chicken (define-macro) (MzScheme 200 will probably be ok, I guess) I don't know wether this is awfully relevant, but it would perhaps be a good idea not to cling to syntax that is based on a slightly contradictory definition as provided in R5RS. felix
