Which allows editable data associated with a particular class instead of the instance. Scripts with static variables are kept in memory indefinitely unless the `@static_unload` annotation is used or the `static_unload()` method is called on the GDScript. If the custom function `_static_init()` exists it will be called when the class is loaded, after the static variables are set.
