/// Returns the indexth element.
/// The index must be non-negative and less than length. Index zero represents
/// the first element (so iterable.elementAt(0) is equivalent to iterable.first).
/// May iterate through the elements in iteration order, skipping the first index
/// elements and returning the next. Some iterable may have more efficient ways
/// to find the element.
/// @description Checks that a RangeError is thrown if this list has fewer than
/// index elements.
