Test That! 0.6.0: A powerful assertion library for Rust

Hi everyone, I just pushed version 0.6.0 of the test assertion crate Test That!. I created Test That! a few months ago as a fork of GoogleTest Rust (of which I am the original author) in order to provide a better developer experience and fix some long standing warts. I'm now looking to move towards releasing version 1.0. To that end, I am looking to get feedback. I need to know whether there are any remaining issues which require breaking changes to fix. Please check it out! See release notes...
