-/// # Example
-///
-/// The Cell type is an example which uses unsafe code to achieve
-/// "interior" mutability:
-///
-/// ```
-/// struct Cell<T> { value: T }
-/// ```
-///
-/// The type system would infer that `value` is only read here and
-/// never written, but in fact `Cell` uses unsafe code to achieve
-/// interior mutability.
