- `C.name` on a class of an import cycle reads the name from the class
object, so the reference gets the class's initialization check: an
early read throws Node's ReferenceError instead of returning the name.
Other classes keep the compile-time name.
- The static field storage of a flag without a class is a shared empty
set, so the self-hosted frontend lowers cycle-initialization.ts.
