That being said, for what it's worth, I've also proposed on the PR on GitHub <https://github.com/php/php-src/pull/6246#issuecomment-719074545> an alternative syntax for a closure that takes no parameters and inherits the full scope: $connection->transactional({ // ... }); So yes, this would be a closure: $a = {}; I'm not sure if this would be considered (additionally, not as a replacement), but I thought it'd be worth mentioning, as it would offer an elegant solution for methods whose body is pretty much only a call to a method wrapping a closure. — Benjamin
