This is excellent. Big thanks to Laszlo! I've been working on a Raphaël-based interactive GUI app in ClojureScript that maintains a big vector of elements, and had just recently started to run into what seemed to be the performance limits of the copy-on-write approach. I'm very optimistic that this feature will allow me to keep using vectors instead of dropping down to mutable host arrays, which is a big win. I can't wait to try this.
