Description

Twig function is_granted does not accept mixed any more for its second argument, instead requiring object or null with a PHP typehint. AuthorizationCheckerInterface::isGranted, where this argument is passed, has no typehint in code and is typehinted as mixed in PHPDoc.

This makes it impossible to have a check in Twig template with code similar to this:

{% if is_granted('ROLE_MY_APP', {foo: 'bar', bar: 'baz'}) %}...{% endif %}

Is this something that was intended, because it doesn't seem so? Upgrade docs mention that the attribute cannot be an array anymore in AuthorizationCheckerInterface::isGranted, but it does not mention that the subject is now required to be a PHP object.

Thank you!
