## Objective Always have `some_system.into_system().type_id() == some_system.into_system_set().system_type().unwrap()`. System sets have a `fn system_type() -> Option<TypeId>` that is implemented by `SystemTypeSet` to returning the TypeId of the system's function type. This was implemented in https://github.com/bevyengine/bevy/pull/7715 and is used in `bevy_mod_debugdump` to handle `.after(function)` constraints. Back then, `System::type_id` always also returned the type id of the function item, not of `FunctionSystem<M, F>`. https://github.com/bevyengine/bevy/pull/11728 changes the behaviour of `System::type_id` so that it returns the id of the `FunctionSystem`/`ExclusiveFunctionSystem` wrapper, but it did not change `SystemTypeSet::system_type`, so doing the lookup breaks in `bevy_mod_debugdump`. ## Solution Change `IntoSystemSet` for functions to return a `SystemTypeSet<FunctionSystem>` / `SystemTypeSet<ExclusiveFunctionSystem>` instead of `SystemTypeSet<F>`. |
