So now we've apparently gone all the way - from a warning issued supposedly just
in case, because a tiny minority of cases where `save-excursion' is used with
`set-buffer' are deemed (by some) to be inappropriate or not ideal, to your
claiming outright that use of `save-excursion' "contradicts the compiler" and
"the compiler says no", it simply cannot be used.
Compiler warnings should be programmers' assistants, not their
masters. That is why we have with-no-warnings. We implement helpful
warnings about constructions that _might_ be mistakes, but that
doesn't mean they are taboo.
