Repro steps

Calling setState in useEffect is marked as an error per react-hooks/set-state-in-effect lint:

  const [, setState] = useState('');

  useEffect(() => {
    // marked as react-hooks/set-state-in-effect error
    setState('test');
  }, []);

However there is no lint error if the setState is wrapped in an useEffectEvent:

  const onSetState = useEffectEvent(() => {
    setState('test');
  });

  useEffect(() => {
    // lint passes
    onSetState();
  });

This provides an easy escape hatch for developers who want to bypass the lint rule.
