/// @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
