Documentation Bug introduced by core23
$environment is of type Twig_Environment, but the property $environment was declared to be of type Twig\Environment. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?

Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a given class or a super-class is assigned to a property that is type hinted more strictly.

Either this assignment is in error or an instanceof check should be added for that assignment.

class Alien {}

class Dalek extends Alien {}

class Plot
{
    /** @var  Dalek */
    public $villain;
}

$alien = new Alien();
$plot = new Plot();
if ($alien instanceof Dalek) {
    $plot->villain = $alien;
}

Bug Best Practice introduced by core23
The expression return preg_split('/(?=<...APTURE) ?: array($text) returns an array which contains values of type array which are incompatible with the documented value type string.
