/// @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
/// when:
/// Left Null: if T0 is Null then:
/// - if T1 is a type variable (promoted or not) the query is false
/// - If T1 is FutureOr<S> for some S, then the query is true iff Null <: S.
/// - If T1 is Null, S? or S* for some S, then the query is true.
/// - Otherwise, the query is false
/// @description Check that otherwise, the query is false. Test some legacy class

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