// Or a simple way :

$tree = new Obernard\PropertyIndexer\PropertyTree([$obj1, $obj2], null, [function($item):string {return $item->id;}]);

// is a complicated way to get the same resulting tree as : 
$tree = new Obernard\PropertyIndexer\PropertyTree([$obj1, $obj2], null, ['id']);

 php
$tree = new Obernard\PropertyIndexer\PropertyTree([$obj1, $obj2], 'value', ['date']);
