| /// @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). |
