В PHP 8.1 будет оператор new в инициализаторах

https://wiki.php.net/rfc/new_in_initializers

Объекты можно будет использовать в качестве дефолтных значений параметров, статических переменных, глобальных констант и в аргументах атрибутов.

А вот со свойствами — нет. Вернее, можно будет использовать через constructor property promotion. Но это в действительности аргументы параметров, а не дефолтные значения свойств. Смотрите сами: 3v4l.org/r9iv4

C константами классов тоже нельзя будет использовать из-за проблем с порядком выполнения инициализации.

Зато этот RFC фактически добавляет поддержку вложенных атрибутов.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
