This will restrict the ``delivery`` options to be either ``standard``,
``expedited`` or ``priority``.

You can also provide enum values to ``enumNode()``. Let's define an enumeration
describing the possible states of the example above::

enum Delivery: string
{
case Standard = 'standard';
case Expedited = 'expedited';
case Priority = 'priority';
}

The configuration can now be written like this::

$rootNode
->children()
->enumNode('delivery')
// You can provide all values of the enum...
->values(Delivery::cases())
// ... or you can pass only some values next to other scalar values
->values([Delivery::Priority, Delivery::Standard, 'other', false])
->end()
->end()
;

.. versionadded:: 6.3

The support of enum values in ``enumNode()`` was introduced
in Symfony 6.3.
