Now Apple, Google, Microsoft and Mozilla will all have to ensure that tricks like (a+b)|0 are executed optimally though.

Yeah, but that's not hard. And there's a spec that makes it extremely clear which tricks are necessary -- no need to reverse-engineer someone else's implementation, and no risk of tricks that work today breaking tomorrow.

The beauty of this approach is that browser vendors don't have to execute these quirky expressions optimally. They are standard JS, so they will already work.
