I have heard it argued that "await" needs higher precedence than we've been considering for yield, but I don't remember the argument. Anyone? Would LeftHandSideExpression be adequate for whatever that argument was?
In the future of promises, we will either continue to use yield as await, or we will provide an (essentially synonymous) await. Either way, it would be good for both of these to have the same precedence, and for that precedence to satisfy both needs.
