I think this is a "macros for macros sake question".

I see that this is a literal approach:

#lang scheme

(define id45 45)
(define idid 'id45)

(define-syntax find-symbol-value
 (lambda (stx)
   (syntax-case stx ()
     ((find-symbol-value)
      (with-syntax
          ((var (datum->syntax #`find-symbol-value 'id45 #f)))
        #`var)))))

(find-symbol-value)

But none of what I have studied or learned (yet?) helps me understand
how to easily generalize the solution. How would you do that?
