/// @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
/// when:
/// Right Object: if T1 is Object then:
/// - if T0 is an unpromoted type variable with bound B then T0 <: T1 iff
/// B <: Object
/// - if T0 is a promoted type variable X & S then T0 <: T1 iff S <: Object
/// - if T0 is FutureOr<S> for some S, then T0 <: T1 iff S <: Object.
/// - if T0 is S* for any S, then T0 <: T1 iff S <: T1
/// - if T0 is Null, dynamic, void, or S? for any S, then the subtyping does not
/// hold (per above, the result of the subtyping query is false).
/// - Otherwise T0 <: T1 is true.
/// @description Check that if T0 is FutureOr<S> for some S but S is not subtype
/// of Object then T0 is not subtype of T1

/// @description Check that if type T0 is not a subtype of a type T1, then
/// instance of T0 cannot be be assigned to the mixin member of type T1.
/// Assignment to instance variable of super class is tested.
