elementAtOrNull

fun <T> Attribute<Iterable<T>>.elementAtOrNull(index: Attribute<Int>): Attribute<T?>
fun <T> Attribute<Iterable<T>>.elementAtOrNull(index: Int): Attribute<T?>
fun <T> Attribute<List<T>>.elementAtOrNull(index: Attribute<Int>): Attribute<T?>
fun <T> Attribute<List<T>>.elementAtOrNull(index: Int): Attribute<T?>

Same as elementAtOrNull, but accepts Attribute and returns a new Attribute.

Calling this function is equivalent to use transform and calling elementAtOrNull in the transformation function.

This is simply a convenience function.
