Announcing Rust 1.30
I'm not a Rust user, but I'm always keeping an eye on it as it drives for improved usability and intuitability. I really admire the open-mindedness and devotion toward improvement that the Rust community displays.<p>One question I have about this update in particular: The raw identifiers syntax addition seems like syntax support for a convention. For example, I could use `r#for` or `_for` to solve the same problem, however, the first requires special syntax and the second doesn't. What does the syntax facilitate that a leading underscore doesn't?
