The byte-compiler should indeed warn you about functions "not known to
be defined", listing things like `case`, `incf`, `first`, `loop`, ...
Tho sometimes instead you'll get a compilation error because the code
uses a macro whose arguments don't have a valid shape when interpreted
as expressions (as in `(destructuring-bind (a . b) foo bar)`).
Also sometimes you'll get warnings about functions "not known to be
defined" which are indeed not functions (e.g. with `(case foo (:plop
bar))` which will complain that `:plop` is not a known function) or
you'll get warnings about unknown variables like `return` or `when`
which are really keywords of the `loop` macro.
