The methods don't return `size` slices, but rather slices of `size` elements. Sorry!
I sure hope this fix is right cc @steveklabnik
I have made changes and built it after that. Please advise, rust-lang#31820

Reference implied that use declarations may appear *only* at the top of blocks and modules, but it is not the case, and the following is valid:
```Rust
fn foo() {
let x = 92;
use baz::bar;
}
```
r? @steveklabnik
As a Rust newbie, I found the book's explanation for why the `filter` closure gets a reference very confusing, and tried to figure out why `filter` is somehow less consumptive than `map` -- but it isn't; that's controlled by `iter`/`into_iter`. I flailed around for a while until @habnabit explained it to me, and in retrospect it is quite obvious :-)
