#### 9.2.44 store-value [Restart] ¶

#### Data Arguments Required:: ¶

a value to use instead (on an ongoing basis).

#### Description:: ¶

The store-value restart is generally used by handlers trying to recover from errors of types such as cell-error or type-error, which may wish to supply a replacement datum to be stored permanently.

#### Examples:: ¶

     (defun type-error-auto-coerce (c)
       (when (typep c 'type-error)
         (let ((r (find-restart 'store-value c)))
           (handler-case (let ((v (coerce (type-error-datum c)
                                          (type-error-expected-type c))))
                           (invoke-restart r v))
             (error ()))))) ⇒  TYPE-ERROR-AUTO-COERCE
     (let ((x 3))
       (handler-bind ((type-error #'type-error-auto-coerce))
         (check-type x float)
         x)) ⇒  3.0
