/**
* @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 not a compile error to apply a mixin that
* contains a super-invocation of a member f1 to a class which has a concrete
* implementation of f1.
