I do not see this work on my copy of CMUCL (19a-release-20 from
Debian) :-/ See below that the behavior of the compiler is independent
of the variable they mention: it always signals an error on undefined
variables, much like ECL. Hence, ext:*top-level-auto-declare* only
controls how interpreted forms behave, and even then it is only a
warning, not an error.

Is this what you meant?
