It seems like $callback can also be of type null; however, parameter $callback of call_user_func() does only seem to accept callable, maybe add an additional type check?

                return $value;
            }
        }
        return static::value($default);
    }

    public static function value($value)
    {
        return $value instanceof \Closure ? $value() : $value;
    }
