| * @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. |
| * ... |
| * However, 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 |
| * @description Checks that if multiple getters with the same name are |
| * inherited actually only one getter is inherited and no static warning |
| * issued. Test type aliases |
