False positives for exception expression

[Chi-teck]

Describe the bug

Since PHP 8.0 expressions can now throw exceptions.
So the code below is valid. However, it triggers Squiz.PHP.NonExecutableCode.Unreachable warning.

Code sample

$input = TRUE;
$input ?: throw new \RuntimeException('Error.');
echo 'The code was executed';

Closing as already fixed via #3777, which will be included in PHPCS 3.8.0.

FYI: the fix for this issue is included in today's PHP_CodeSniffer 3.8.0 release.

As per #3932, development on PHP_CodeSniffer will continue in the PHPCSStandards/PHP_CodeSniffer repository. If you want to stay informed, you may want to start "watching" that repo (or watching releases from that repo).
