I've got to admit Steve, you really spiked my blood pressure this morning with a statement like "we're changing the module system." -- I'm outraged that you would link to this well reasoned, well written RFC that has such a clean and simple migration story! ;-)

I'm actually most hyped about `#![feature(crate_visibility_modifier)]` to be honest. I know it's essentially just an alias for pub(crate), but I'm all about typing less parens in my item definitions! I didn't know about the other `pub(...)` modifiers for the longest time, but they've been so useful for things like games programming, where the entire point of the exercise boils down to "cross cutting concerns" and "eh you've got a &mut Player anyways, just reach in there and poke at the state!"

The `../mod.rs` change is also quite nice. I mean, at the end of the day it'll only save me a `mv` command and a refresh of my directory listing in vim, but sometimes those small context switches can have a surprisingly large impact on flow; since now I'm thinking about filesystems and module trees rather than the problem at hand.

Hehe, I'm glad you're feeling positive about it. It took a lot of blood and tears to reach this point, honestly.

Yeah, as you say, it feels minor, but hopefully, a lot of tiny ergonomic changes will end up feeling significantly better. It's also why the epoch concept is important; it gives us a way to talk about how all these little changes every six weeks build into something much bigger and nicer.
