The documentation in mem::forget says "...or call `process:exit`..."
instead of `process::exit`.

/// `forget` is not marked as `unsafe`, because Rust's safety guarantees
/// do not include a guarantee that destructors will always run. For example,
/// a program can create a reference cycle using [`Rc`][rc], or call
-/// [`process:exit`][exit] to exit without running destructors. Thus, allowing
+/// [`process::exit`][exit] to exit without running destructors. Thus, allowing
/// `mem::forget` from safe code does not fundamentally change Rust's safety
/// guarantees.
