fn failing_test1() -> Result<()> {
    // wrong contents, 1 != 2
    expect_some_eq!(Some(1), 2);  // returns early
    Ok(())  // won't be reached
}

fn failing_test2() -> Result<()> {
    // first arg is None
    expect_some_eq!(None::<i32>, 2);  // returns early
    Ok(())  // won't be reached
}
