Hi,

Do you think it would be hard or wrong to add `array_nth`? I've had more 
trouble with that as the in-place implementation is usually pretty 
unreadable, e.g.

     array_slice(array_values($array), $offset, 1)[0] ?? null

I understand this need is less common, especially compared to 
`array_first`. But I also suspect that an in-engine implementation might 
have more performance gains compared to an userland one.

BR,
Juris
