Description:
------------
PHP 8.0 breaks any existing code with a class named "match", which became a reserved word for some reason.

PHP 7.0 intentionally loosened such reserved word restrictions, per the original release announcement here:

https://www.php.net/manual/en/migration70.other-changes.php

It would be nice if PHP continued in that vein to avoid more variations of this problem.

Parser failure is demonstrated with a minimal repro here:

A quick google search reveals at least two major projects (PHPUnit and MediaWiki) affected by this change - here's a handful of examples from a quick google search:

- https://github.com/sebastianbergmann/phpunit/issues/4373
- https://github.com/wikimedia/mediawiki-vendor/blob/master/ruflin/elastica/lib/Elastica/Query/Match.php
- https://github.com/mindplay-dk/timber/blob/master/src/Match.php
- https://github.com/zweifisch/php-pattern-matching/blob/master/match.php
- https://github.com/extesy/foosball/blob/master/match.php


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

class Match {}

class Matcher
{
    public function match(): Match {}
}

$matcher = new Matcher();

$match = $matcher->match();


Expected result:
----------------
It would be nice if this could be treated as a bug, and could be fixed with a minor release, such that packages that were broken by this change can be versioned correctly against e.g. PHP ^8.0.1, before everyone goes and starts renaming classes and functions.
