I’m registering a custom Carbon macro in my Laravel’s AppServiceProvider

Carbon::macro('itFormat', static function () {
    return ucwords(self::this()->translatedFormat('l d/m/Y'));
});

But PHPStan insists that, in this code, self is referred to the AppServiceProvider itself

Call to an undefined static method App\Providers\AppServiceProvider::this()

An easy solution (found here) should be to use a non-static function and a PHPDoc annotation targetting $this, such as

Carbon::macro('itFormat', function () {
    /** @var Carbon $this */
    return ucwords($this->translatedFormat('l d/m/Y'));
});

But this is in contrast to the Carbon’s documentation itself, saying:

Note that the closure is preceded by static and uses self::this()
(available since version 2.25.0) instead of $this. This is the
standard way to create Carbon macros, and this also applies to macros
on other classes

Which may be the proper PHPDoc annotation for the “self in static function” way?
