Problem rsx macro fails to parse with confusing error message

Steps To Reproduce This code

use dioxus::prelude::*;

fn main() {
    launch(app);
}

fn app() -> Element {
    rsx!(
        div { class: "game",
            div { class: "board", board }
            div { class: "state", game.with(|g| g.state().to_string()), }
        }
    )
}

produces this error when running dx serve:

The errors need to be better here but expressions must be wrapped in curly braces.

Thanks, that is very helpful. I am porting from 0.4 and trying to follow the migration guides, but I don't recall seeing this information.

Anyway, that seems to have been the missing piece for me to complete my migration. Thanks again!
