;; As I could find from chicken and guile, string-fill! should modify
;; any string, not only one given with (make-string) only, which creates immutable strings
;;
;; This behaviour should be somehow documented and here it is:
;; If we make a string like '(define s "foo")' it will be immutable by default and that
;; can't be changed. On other hand, if we do something like:
;; (define s (make-string 10))
;; (set! s (string-copy "foo"))
;; 's' will have "foo" value, have length of 3 characters and _will_ be mutable, e.g.
;; '(string-set! s 0 #\m)' will not fail and result will be "moo".
;;
;; Should it be seen as bug?
