## Freezing
Lending an immutable pointer to an object freezes it and prevents mutation.
`Freeze` objects have freezing enforced statically at compile-time. Examples
of non-`Freeze` types are `@mut` and [`RefCell<T>`][refcell].

Mutable managed boxes handle freezing dynamically when any of their contents
are borrowed, and the task will fail if an attempt to modify them is made while
they are frozen:
~~~~
let x = @mut 5;
let y = x;
{
let z = &*y; // the managed box is now frozen
// modifying it through x or y will cause a task failure
}
// the box is now unfrozen again
