This op is used by the Music Transformer model.

This would vastly help the Dev experience for game developers 😄 They cansimply host a local server that hosts their game, and the debugger can just try to grab it and auto run 😄

I think using this pattern doesn't make it obvious for how users might expand on the example. If a user does decide to use a struct as their model, the code written in update and view also need to updated, while not always obvious. For example, a user might try to do this:

struct Model {
    name: String,
}
fn view(model: &Model) -> Node<Msg> {
    div![
        button![model],
