handler-case form &rest cases[Macro]

(handler-case form { (type ([var]) body) }* )

Executes 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.
