(let ((combo (gtk-combo-box-entry-new-text)))
  (for-each (lambda (text)
              (append-text combo text))
            '("foo" "bar" "baz"))
  
  (let ((model (get-model combo)))
    (let loop ((iter (get-iter-first model)))
      (if iter
          (begin
            (format #t "~A\n" (get-value model iter 0))
            (loop (iter-next model iter)))))))
