But what happens if you try to REVERSE a syntax-object wrapping a list?
You can't - 

Overall your essay is illuminating, but reversing a syntax-object representing a list is easy in an R6RS-conforming implementation.

(define (reverse-wrapped-list obj)
  (syntax-case obj ()
    ((e ...) (reverse #'(e ...)))))

...though maybe your whole point was that there should be more basic tools available (standardized) for de-structuring instead of the heavy-handed syntax-case?
