From: vovan-ve at yandex dot ru Operating system: PHP version: 5.5.9 Package: Scripting Engine problem Bug Type: Bug Bug description:Cannot access static::class in lambda, writen outside of a class Description: ------------ Since PHP 5.4 a closure can be bound to a object of a class to work like a method. Since PHP 5.5 class name can be fetched with special syntax SomeClass::class, like a pseudo-constant with name 'class'. This second feature does not work in a lambda, writen outside of a class. It cause syntax error. Test script in a sandbox: http://3v4l.org/XO0bZ May be, related with #66622 ?
