(handler-case form &rest cases) | Function: (HANDLER-CASE form { (type ([var]) body) }* ) Execute FORM in a context with handlers established for the condition types. A peculiar property allows type to be :NO-ERROR. If such a clause occurs, and form returns normally, all its values are passed to this clause as if by MULTIPLE-VALUE-CALL. The :NO-ERROR clause accepts more than one var specification.
