/**
 * @assertion Mixin application semantics is mostly unchanged, except that it's
 * a compile-time error to apply a mixin to a class that doesn't implement all
 * the 'on' type requirements of the mixin declaration, or apply a mixin
 * containing super-invocations to a class that doesn't have a concrete
 * implementation of the super-invoked members compatible with the
 * super-constraint interface.
 *
 * @description Checks that it is a compile error if a mixin is applied to a
 * class that does not implement all the 'on' type requirements of the mixin
 * declaration.
