 * @assertion Let S be a class, M be a mixin with required superinterfaces
 * T1, . . . , Tn, combined superinterface MS, implemented interfaces
 * I1, . . . , Ik and members as mixin member declarations, and let N be a name.
 * ...
 * The mixin application of M to S with name N introduces a new class, C,
 * with name N, superclass S, implemented interface I1, . . . , Ik and members
 * as instance members.
 * @description Checks that it is no compile error to derive a mixin from a
 * class which has a superclass other than Object, even if mixin has all of its
 * explicitly defined getters
