Edit report at https://bugs.php.net/bug.php?id=79942&edit=1 ID: 79942 Updated by: sjon@php.net Reported by: sjon@php.net Summary: b/c break: new\class now fails -Status: Verified +Status: Closed Type: Documentation Problem Package: Class/Object related Operating System: archLinux PHP Version: 8.0.0beta1 -Assigned To: +Assigned To: sjon Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2020-08-10 09:20:41] nikic@php.net I have added a mention of this case to the UPGRADING note: https://github.com/php/php-src/commit/e81ad4089e7435bec8dc075089e9c47851b8ddb7 ------------------------------------------------------------------------ [2020-08-07 11:51:42] cmb@php.net 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.
