As long as the animation can be driven off of state I think you can just use the `.animation()` view modifiers. We just updated our animation case study to have the circle change colors on a timer, which is driven off of effects (see [here](https://github.com/pointfreeco/swift-composable-architecture/pull/198)).

Do you have an example of animation that doesn't fall into this simple use case? Could you share a lil demo app to show what you are dealing with?
