I'd love to compile such a thing, but doing it properly would involve both cataloguing every change and recording the rationale for each. And because the rationale for changes is so dependent on the context of the-language-as-it-was-at-that-moment-in-time, random access of the archive would leave your understanding incomplete. For example, I just said that we removed `Either` because nobody was using it and because it was structurally a complete duplicate of `Result`... but I omitted the fact that `Result` was almost universally shunned at the time as well, in favor of `Option`. :P

Part of me wonders if the best way to do it wouldn't be to to start at Rust 1.0 and go on a tour backwards through history, i.e. "here's a great language, now let's all make terrible decisions to make it worse!" :)
