Description:
------------
It's no longer to create an object from a specific namespace without a trailing space after the 'new' keyword. This change is not documented as b/c incompatible change in the NEWS or UPGRADING file. Somewhat inconsistently, `new$x` still works: https://3v4l.org/JSAFD


originally found as https://3v4l.org/ZMgiM



Test script:
---------------
<?php

class x {}
new\x;

Actual result:
--------------
Fatal error: Uncaught Error: Undefined constant "new\x" in /in/KsknY:4

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.

I have added a mention of this case to the UPGRADING note: https://github.com/php/php-src/commit/e81ad4089e7435bec8dc075089e9c47851b8ddb7
