I haven’t done a lot of work with `rand`, but I do use it in the book. The “give me a random number” case ends up taking all this stuff:

```rust
extern crate rand;

use rand::Rng;

fn main() {
    let secret_number = rand::thread_rng().gen_range(1, 101);
}

```

It’d be nice to have some kind of convenience function for “just do the right thing and give me some numbers in this range” rather than needing to `use` a trait.
