The announcement also makes it very clear that 1.4 isn't just a rust port of 1.3. Rust is my favorite language and it can be a bit faster than other systems languages in the right circumstances (because the compiler can make optimizations based on assumptions that wouldn't hold without the borrow checker), but numbers like those seem far more likely to be the result of other changes than the language shift.

Which one is it?
