/**
 * @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
 * @static-clean
