Hi, If I'm following properly, iterate is now a unique name that can be used on any object as per July 24 meeting notes [1]. It led the decision to remove the iterate trap on proxies [2]: "Removed ''iterate()'' trap as iterators can be defined on any old object via an ''iterate'' unique name. See discussion at [[harmony:iterators]]. A proxy will intercept the request for its iterator via the ''get'' trap, which is passed the unique ''iterator'' name as argument."
What about making "enumerator" a unique name and remove the enumerate trap too? Proxies that want to redefine the behavior of for-in loop can just decide to return a different iterator than the target one.
