Preload without Class

Basically preload is written a sub class of XCube_ActionFilter. But, You may write area outside of bracket. The Coding Style Guide recommends Class-Driven, so this is not standard in Cube. But, it's useful for light-weight customizing & duplicatable modules. Especially duplicatable modules can not obey the naming convention of Legacy's ActionFilter, because it's impossible to decide their namespace before. Code outside of class is executable without namespace.
