The pseudocode for checking if the object has a [[Handler]], and if that [[Handler]] has a trap, and then invoking the trap could all be factored out into a [[Trap]] (or something) internal method, which takes a trap name, and a list of arguments to pass to the trap, and returns whether or not the object has the trap, and if so, also a return value from the trap. This would make for a very concise and clear spec with regard to proxies, and it would be relatively easy to update the current proposal to do this.
