I understand that R7RS got rid of syntax-case and standard Scheme is back to syntax-rules only (which is another thing I like about Common Lisp: the standard has been in existence for 23 years).

I'm reminded of this article (https://fare.livejournal.com/189741.html), where this Common Lisp macro:

    (defmacro nest (&rest r) (reduce (lambda (o i) `(,@o ,i)) r :from-end t))

Has to turn into this in Racket (which isn't quite Scheme):

    (define-syntax (nest stx)
      (syntax-case stx ()
        ((nest outer ... inner)
         (foldr (lambda (o i)
                  (with-syntax (((outer ...) o)
                                (inner i))
                    #'(outer ... inner)))
                #'inner (syntax->list #'(outer ...))))))

And was incredibly difficult to reason about. And that author likes Racket.
