Well in Rust ypu couldn't have = return the new value in general anyway, because it's been moved. So even if chained assignment did work, it'd only work for copy types, and really, a feature that only saves half a dozen characters, on a fraction of the assignments you do, that can only be used a fraction of the time, doesn't seem worth it at all.
