// Validate the following test from section 12 ("Mixins") of the spec:
//
//     "Let M_A be a mixin derived from a class M with direct superclass
//     S_static.
//
//     Let A be an application of M_A.  It is a static warning if the
//     superclass of A is not a subtype of S_static."

// In this test, M is declared as `class M extends ... with G {}`, so
// `S_static` is the unnamed mixin application `... with G`.  Since this
// unnamed mixin application can't be derived from, all the cases should yield
// a warning.
