- with-exception-handler handler thunkprocedure
Returns the result(s) of invoking thunk. The handler procedure is installed as the current exception handler in the dynamic context of invoking thunk.
Example:
(call-with-current-continuation (lambda (k) (with-exception-handler (lambda (x) (k '())) (lambda () (car '()))))) ;=> '()
Note that the handler procedure must somehow return non-locally out of the dynamic extent of the with-exception-handler form, because returning normally will signal yet another exception and thus result in non-termination.
