Hi internals, I've opened voting on https://wiki.php.net/rfc/new_in_initializers. Voting will close on 2021-07-14.
Note that relative to the original RFC, new support is limited to parameter default values, attribute arguments, static variable initializers and global constant initializers, and not supported in property initializers and class constant initializers. The discussion thread https://externals.io/message/113347 has some extensive information on how we got here. Regards, Nikita
