Description: ------------ phpcs seems to mis-interpret the new static `::class` constant (new in PHP 5.5 [1]). In my case this manifests as several "Undefined index" notices when running phpcs on code like class Foo { public function bar() { return Bar::class; } } We are using the PSR2 standard but I suppose that applies to others as well. Test script: --------------- class Foo { public function bar() { return Bar::class; } } Expected result: ---------------- No notices being reported. Actual result: -------------- Several notices like this (paths shortened to the relevant part) PHP Notice: Undefined index: scope_opener in [...]/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards /PSR2/Sniffs/Classes/ClassDeclarationSniff.php on line 108 PHP Stack trace: PHP 1. {main}() [...]/vendor/squizlabs/php_codesniffer/scripts/phpcs:0 PHP 2.

I don't want to disguise the promised attached notices as a patch, so I pasted them here: http://paste.fedoraproject.org/33033/37690095/
