Bug->Doc #79942 [Opn->Ver]: b/c break: new\class now fails

Edit report at https://bugs.php.net/bug.php?id=79942&edit=1 ID: 79942 Updated by: cmb@php.net Reported by: sjon@php.net Summary: b/c break: new\class now fails -Status: Open +Status: Verified -Type: Bug +Type: Documentation Problem Package: Class/Object related Operating System: archLinux PHP Version: 8.0.0beta1 Block user comment: N Private report: N New Comment: That behavioral change is due to "RFC: Treat namespaced names as single token"[1]; new\x is now a single token (same for some other operators, e.g. instanceof). That needs to be documented. > Somewhat inconsistently, new$x still works […] TIL, but actually not really surprising, since the scanner "automatically" sees two tokens here.
