/**
 * @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)

 * 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 if type T0 is Null and T1 is FutureOr<S> for some S,
 * and Null is subtype of S then T0 is subtype of T1.
