Topic: Extra `}` do not cuase error in new compiler

The new compiler does not seem to error when there are extra }, for example in the code:

app [main!] {
    pf: platform "https://github.com/lukewilliamboswell/roc-platform-template-zig/releases/download/0.4/6XA8JLWhmG1FSgb8GxPjBs9cGrtRqopohR3KAHYo722z.tar.zst",
}
import pf.Stdout
main! = |_args| {
    Stdout.line!("Hello world")
    Ok({})
}}

It's not a bug, it's a feature :smile:. To be fair this should be some kind of error message, but with "inform, don't block" it's ok that it runs.

yeah we definitely should report this at compile time though! Can you open a GitHub issue for it @Jamie?

Would this be a good first issue to work on? It looks like we already do similar logic for type errors during roc run so we could follow that same idea here and exit early depending on if allow-errors is passed
