I see how this errata happened now, the book has the main function on p. 24 as:

```auto
fn main() {
println!("Hello, what's your name?");
println!("Hello, {}", what_is_your_name())
}

```

But the [online code example](http://media.pragprog.com/titles/hwrust/code/FirstStepsWithRust/treehouse_guestlist_problem/src/main.rs) throws the function output into a variable:

```auto
fn main() {
    println!("Hello, what's your name?");
    let name = what_is_your_name();
    println!("{:?}", name);
}

```
