 // The mock compiler of dart2js used to make the compiler crash on
 // this program.
 //
 // The SSA backend generates a call to a throwNoSuchMethod helper for
 // the access to `foo`, and we used to not infer return types of
 // helpers, so we did not know throwNoSuchMethod was not returning.
 // As a consequence, all operator[] had to be compiled, and due to
 // missing backend dependencies, some of them were not resolved.
