+ *
+ *  This test requires:
+ *  - dotty-interfaces to be present at compile-time
+ *  - dotty-interfaces and dotty to be present at run-time
+ *
+ *  Since the ABI of dotty-interfaces is stable, this means that users can write
+ *  code that works with multiple versions of dotty without recompilation.
