// Pins the C3 gap (PLAN-C C0.2b): the `#foreign` library/unit ref is
// DECORATIVE today — `nosuchunit` names nothing anywhere, yet this
// compiles and the symbol resolves globally (the unit's objects are in
// the program; the ref is never consulted). After C3 this is a
// compile-time diagnostic: a #foreign ref must name a #library or a
// named `#import c` unit.
