- `extern` now requires `unsafe extern`, but in turn allows functions within it to be marked as `safe`. Add examples to both effects within the text, and update listing numbers accordingly. - `#[no_mangle]` now requires `#[unsafe(no_mangle)]` These are all backwards-compatible, so we can opt the chapter into using the new rules without issue.

This makes for a nicely simpler introduction of this feature!

GitHub is… confused. I am going to close and reopen this PR and see if that helps; if not I will simply recreate it. Couldn't re-open it, so I recreated it as #4111. |
