/// @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 class S
/// @author sgrekhov@unipro.ru

/// @description Check that if type T0 not a subtype of a type T1, then instance
/// of T0 cannot be used as a return value of type T1. Return value is tested.
