Re: [RFC] [Discussion] Bound-Erased Generic Types

Voting is now open. The [VOTE] thread is here: https://news-web.php.net/php.internals/131236 The vote started on 2026-06-14 at 16:50 UTC and ends on 2026-06-28 at 17:00 UTC. Two votes on the RFC page: 1. Primary, 2/3 majority: accept the RFC. 2. Secondary, simple majority, conditional on the primary: variance marker syntax. Thanks again to everyone who contributed to the discussion. Regards, Seifeddine.
