I have found solution which I can use while I have not learned enough
guile internals to make better one

(define (test s v)
  (if (not (symbol? s))
      (error "s must be symbol"))
  (if (not (integer? (eval s)))
      (error "s must evaluate to integer"))
  (let ((x (list 'set! s v)))
    (eval x)))

(define var 0)
var => 0
(test 'var 10)
var => 10

Now I will try to find more efficient ways to do that in C.
