        // leave the a's type empty cause rustc reject compile
        Ok(b'+'
            .repeat_range(a.0..a.0 + 1)
            .then(b'-'.repeat_range(a.1..a.1 + 1)))
    });

    assert_eq!(
        BytesCtx::new(b"3,0+++").ctor(&re)?,
        ((3, 0), ([43, 43, 43].as_slice(), [].as_slice()))
