I vote for immediately changing CATCH and THROW to generate an error
|Use *CATCH and *THROW instead, see MC:LSPMAI;CATCH QUERY for info.|
or something like that.  CATCH QUERY should indicate how to emulate
all forms of old CATCH/THROW code using the new *CATCH/*THROW/CATCHALL.
Persons running NIL code can write macros that map CATCH and THROW to
*CATCH and *THROW, thus there is no reason to install CATCH and THROW
as built-in synonyms for *CATCH and *THROW for several months.  Lusers
running old code during this time will thus be pointed to needed info
for easily upgrading the code, while experienced NIL users will be
careful not to load faulty code in with their NIL stuff.
