## 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
