function Component(props) {
  // x is mutated conditionally based on a reactive value,
  // so it needs to be considered reactive
  let x = [];
  if (props.cond) {
    x.push(1);
  }
  // Since x is reactive, y is now reactively controlled too:
  let y = false;
  if (x[0]) {
    y = true;
  }
  // Thus this value should be reactive on `y`:
  return [y];
}
