In node 3.7.1 "The 'type-of-animal' Function in Detail"

On line 3309 (emacs v27.1, and in v26.3 it's on line 3307), I think there is an extra parenthesis in the code:

```
        (if (equal characteristic "fierce")
            (message "It is a tiger!")))
```

Is this *info* designed to write like this or just a typo?
