I don't understand the Travis errors. They are failing claiming I am not using use std::ascii::AsciiExt;, but only in nightly and beta. I am using that import though, and when I build with nightly/beta locally, everything is fine.

It's because starting in Rust 1.23 (which is currently in beta), the methods that were on AsciiExt are now inherent methods, and so the imported trait is not "used" on >=1.23. You need to slap a #[allow(unused)] on the use std::ascii::AsciiExt line.

Odd that I can't reproduce it locally, but it should be fixed now.

Thanks, these are really useful!
