This warning is triggered, because the analyzer checks everything. In contrast,
dart2js does only compile (and type check) what it thinks it needs.

Currently, dart2js is not tested for warning, but this would fail if we did.

If you want to check that dart2js and the VM do a runtime check, you would have
to create an instance of C and assign to the field.
