Hello internals, An update on timing: this RFC will no longer target PHP 8.6. I asked the 8.6 Release Manager about the feature freeze. The effective cutoff is not the beta1 announcement on August 13 but the creation of the beta1 tag, which happens on Tuesday, August 11, mid-morning US Central time. A vote opened today would close on August 13, after the tag exists, so inclusion in 8.6 is not possible. I will therefore not reopen the vote, and the Intent to Vote I posted on July 23 is withdrawn. I have retargeted the RFC to the next PHP version, whether that is 8.7 or 9.0. RFC text is otherwise unchanged and remains final: https://wiki.php.net/rfc/literal_scalar_types Seifeddine
