Laravel Mail - New methods with interesting parameter passing-CodePudding

I am wondering here by the parameter passing in the new Laravel Mail class. My IDE (VSCode) also underlines the parameter and throws the following error: syntax error, unexpected ':', expecting ')'

public function envelope()
{
    return new Envelope(
        subject: 'Subject', // <-- the key subject
        from: '[email protected]', // <-- the key from
    );
}

Nevertheless, it works. It's probably a new PHP specification that I don't know yet. What is it called and does it work? And how can I teach my IDE that it is not an error?
