* @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
* when:
* Left Type Variable Bound: T0 is a type variable X0 with bound B0
* and B0 <: T1
* @description Check that if T0 is a type variable X0 with bound B0 and
* B0 <: T1 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
* @author
* This test is generated from left_type_variable_bound_A01.dart and
* return_value_x01.dart.
* Don't modify it. If you want to change this file, change one of the files
* above and then run generator.dart to regenerate the tests.
