Reproduziere das Verhalten von declaration emit aus dem verlinkten Playground mit dem im issue gezeigten enum und explizit typisierten const. Verfolge den declaration-emit-Pfad für diese Deklaration und überprüfe, dass die generierte Deklaration den manuell geschriebenen Typ beibehält, statt den Initializer-Ausdruck zu verwenden.
