This test keeps the module and caller in the same compilation unit, so it does not seem to exercise whether the declare-variant metadata survives a `.mod` round-trip. Is separate-compilation support intended here? If yes, could we add a true two-file/module round-trip test? If not, it may be worth documenting the limitation or adding a TODO test so this does not silently fall back to the base procedure.
