 //! There are several structs that are useful for slices, such as `Iter`, which
 //! represents iteration over a slice.
 //!
-//! ## Trait Implementations
+//! ## Traits
+//!
+//! A number of traits add methods that allow you to accomplish tasks
+//! with slices, the most important being `SliceExt`. Other traits
+//! apply only to slices of elements satisfying certain bounds (like
+//! `Ord`).
+//!
+//! An example is the `slice` method which enables slicing syntax `[a..b]` that
+//! returns an immutable "view" into a `Vec` or another slice from the index
+//! interval `[a, b)`:
+//!
+//! ```rust
+//! fn main() {
+//!     let numbers = [0, 1, 2];
+//!     let last_numbers = &numbers[1..3];
+//!     // last_numbers is now &[1, 2]
+//! }
+//! ```
+//!
+//! ## Implementations of other traits
 //!
 //! There are several implementations of common traits for slices. Some examples
 //! include:
 //!
 //! * `Clone`
-//! * `Eq`, `Ord` - for slices whose element type are `Eq` or `Ord`.
+//! * `Eq`, `Ord` - for immutable slices whose element type are `Eq` or `Ord`.
 //! * `Hash` - for slices whose element type is `Hash`
 //!
 //! ## Iteration
 //!
-//! The slices implement `IntoIterator`. The iterators of yield references
-//! to the slice elements.
+//! The method `iter()` returns an iteration value for a slice. The iterator
+//! yields references to the slice's elements, so if the element
+//! type of the slice is `isize`, the element type of the iterator is `&isize`.
 //!
-//! ```
-//! let numbers = &[0, 1, 2];
-//! for n in numbers {
-//!     println!("{} is a number!", n);
+//! ```rust
+//! let numbers = [0, 1, 2];
+//! for &x in numbers.iter() {
+//!     println!("{} is a number!", x);
 //! }
 //! ```
 //!
-//! The mutable slice yields mutable references to the elements:
-//!
-//! ```
-//! let mut scores = [7, 8, 9];
-//! for score in &mut scores[..] {
-//!     *score += 1;
-//! }
-//! ```
-//!
-//! This iterator yields mutable references to the slice's elements, so while the element
-//! type of the slice is `i32`, the element type of the iterator is `&mut i32`.
-//!
-//! * `.iter()` and `.iter_mut()` are the explicit methods to return the default
-//!   iterators.
-//! * Further methods that return iterators are `.split()`, `.splitn()`,
-//!   `.chunks()`, `.windows()` and more.
+//! * `.iter_mut()` returns an iterator that allows modifying each value.
+//! * Further iterators exist that split, chunk or permute the slice.
