| /// @assertion We define inherited(J, K) to be |
| /// the set of members m such that all of the following hold: |
| /// • m is accessible to K and |
| /// • A is a direct superinterface of J and either |
| /// – A declares a member m or |
| /// – m is a member of inherited(A, K). |
| /// • m is not overridden by J. |
| /// ... |
| /// If the above rules would cause multiple members m1 , . . . , mk with |
| /// the same name n to be inherited (because identically named members existed |
| /// in several superinterfaces) then at most one member is inherited. |
| /// If some but not all of the mi , 1 ≤ i ≤ k are getters none of the mi are |
| /// inherited, and a static warning is issued. |
| /// @description Checks that if multiple members with the same name are inherited |
| /// but not all of them are getters then a compile error occurs |
