;;;; A macro in an imported package.
;;;;
;;;; The expander collects defmacros from the prelude and from the file being
;;;; compiled. Collecting them from a package would mean resolving that
;;;; package's own imports at the Form level, before Load runs -- a second
;;;; import resolver -- so it does not, and says so. Left alone the call would
;;;; arrive at the checker as an unknown name, which is the failure shape this
;;;; codebase refuses to ship. Never built: the refusal is the test.
