The ? operator changed how I write Rust

Propagate, don't panic

Early Rust code is full of match arms unwrapping results. The ? operator collapses that into a single readable line while keeping errors explicit.

fn read_config(path: &str) -> Result<Config, Error> {
    let raw = std::fs::read_to_string(path)?;
    let cfg = toml::from_str(&raw)?;
    Ok(cfg)
}
