> We can write: q.remove(); If that method returns, many tools will complain that the returned value is ignored

  That's a bug in the tools. IntelliJ doesn't and neither does Sonar Cloud.

    IntelliJ complains if you don't check certain values (e.g. `file.delete()`). It's not a bug, it's extremely helpful.

      Interesting. It does do that for file.delete() but not for remove(). That's because it's smart enough to know which values are important. In the case of delete() you would want to check the result. So the warning is good and using an underscore to ignore it would actually be a problem. In the case of remove() we don't really need the result.
