Date: 19 Nov 1985 1641-PST From: Rem@IMSSS 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.
