Should we add @SuppressWarnings("unused") to avoid (Eclipse) IDE warnings?

If you send a PR for that, I will merge it. :-)
Error Prone doesn't warn about an unused variable if its name begins with unused.
Eventually I might want to add Error Prone's @CanIgnoreReturnValue to methods like this nextName, and then we wouldn't need to have this assignment. But that would mean introducing a dependency on Error Prone's annotations artifact.
