Examples
This example shows that items() returns an Iterable view of the Vector. The Iterable will produce the values of the Vector at the time it's iterated.
$v = Vector {'red', 'green', 'blue', 'yellow'};
// Get an Iterable view of the Vector
$iterable = $v->items();
// Add another color to the original Vector $v
$v->add('purple');
// Print each color using $iterable
foreach ($iterable as $color) {
echo $color."\n";
}
// This wouldn't work because the Iterable interface is read-only:
// $iterable->add('orange');
