afaik there's no plans to stabilize box in the near future, soooo calling it "reserved for future use" since that's not a lie

While I'm here, this is missing types, traits, generic lifetimes, loop labels and macro matchers. Yes, the last two are kind of obscure.
It is probably better to make this 'identifiers such as names of functions ...' and just include types, traits and lifetimes.

Current module, and some extra stuff in import paths.

'reference and raw pointer'?

Perhaps say what it does, e.g., 'makes a closure copy/move its captures from the environment'.

Should all reserved keywords be collected together at the end?

Since it's looking to be stabilised soon, pub(in path).

We're going to put pub(thing) in the newest features appendix, which isn't going to be in print, so I think we should leave it out of the printed keyword index. Actually, I might be convinced otherwise, since there are other things in this keyword index we don't really talk about in the book.... idk. I'm going to leave it out for now at least until it's stable.
Also reorder by likelihood of encountering, ish.

@matthewjasper thank you for your comments, as always! take another look? :) ❤️ |

$crate? (macros 2.0 can't come soon enough).

o.O i had no idea that even existed

'Alias for implementer type'? or maybe even more words.
I'm not planning on doing those. I'm envisioning this index to be "what is this word for?" and a quick explanation... for the print book, we'll be doing a real index. For the online book, it'd be nice to have search someday... there's always going to the one-page print view and ctrl-f.... |
Mostly cribbed from the syntax index in the old book. I might have messed up or not been as descriptive as I could be, even in a short definition... I'd love reviews! ❤️
