/// @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 methods with the same name are
/// inherited actually only one method is inherited and no static warning
/// issued. Test type aliases
