Most of it LGTM. Let's fix/discuss the rest.

☔ The latest upstream changes (presumably #10652) made this pull request unmergeable. Please resolve the merge conflicts.

[blyxyas]

I think the latest commit fixes the issues shown in the reviews.

[flip1995]

LGTM.

Rebased and formatted.

I'm concerned that PRs for the new chapters might get blocked by our link checker, because those new chapters that are linked in here are not yet upstream. But in the meantime we can just replace them with FIXMEs.

If anything should fail during merge, feel free to r=me after swapping out the links with FIXMEs.

print.html:2183: broken link - `development/define_lints.html`
development/method_checking.html:191: broken link - `development/define_lints.html

Should be fixed after #10595 is merged.
