* @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
* when:
* Right Top: T1 is a top type (i.e. Object?, dynamic, or void)
* @description Check that if type T1 is an Object then T0 is a subtype of a
* type T1
* @author
* @description Check that if type T0 is a subtype of a type T1, then instance
* of T0 can be be used as a return value of type T1

* This test is generated from right_top_A01.dart and
