/// @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 there is no static warning if multiple members
/// with the same name are inherited and all of them are getters or all of
/// them are methods.
