How is this syntax macro style improve on a more direct and simple
standard scheme implementation of:
(define (number/base base)
(lambda (lst)
(let loop ((digits lst)
(accumulator 0))
(if (null? digits)
accumulator
(loop (cdr digits)
(+ (car digits) (* accumulator base)))))))
This amalgam of 'match' and 'define-syntax's style '...', and
'destructuring-bind' syntax just seems to add complexity to a language
whose prime benefit is the clarity of its explicitness and lack of
syntax.
