    MacLISP and ZetaLisp (Symbolics LISP Machine) had/have that feature too.
    CATCH-ALL was/is a macro that generates the appropriate (:CATCH NIL form).
    But the ZetaLisp manual says if you think you need this you probably want
    UNWIND-PROTECT instead.
Just to set the record straight, Zetalisp does not contain CATCH-ALL.
