@carols10cents i pushed 19.5; I dropped move closures since they were discussed before. We should figure out what we want with them overall, but I think for the purposes of this ticket, it's not a big deal.

@steveklabnik i got through the end of fully qualified syntax today, i gtg for now. I know tomorrow is Meeting Day, but if you find yourself with time in between, feel free to start reviewing my edits from the start of ch 19 and I'll see if I can keep ahead of you.... there are some TODOs I put in there where I'm really not sure of what I'm doing. Especially check the Lifetime Subtyping section, I was kind of lost so make sure I didn't make up an untrue story that makes more sense in my head than what actually happens while trying to clear it up....

[steveklabnik]

Yeah, even though it is, I really want to make sure I stay ahead of you here. ❤️

[steveklabnik]

Subtyping section looks good to me 😄

I pushed ab1b71f to fix the FIXMEs, what do you think?

@carols10cents

is what i have regarding the beta link; WDYT? It's very.... basic

[carols10cents]

it's kinda.... scary? idk. maybe something just as saturated but not aaaaa error red? i feel like most any color would still stand out since everything else is b&w... unless you were going for scary :)

[steveklabnik]

I wasn't going for anything; I'm just real bad at visuals, heh

[steveklabnik]

Okay i did some stuff e8a9c6b

(yay twitter bootstrap)

re: put an image of the cover on https://doc.rust-lang.org/nightly/book/ ? I've sent an email to no starch to triple check that this is okay with them

Update: this is blocked on stuff; we may or may not be able to get it into beta, can always backport later though
