If I'm following properly, iterate is now a unique name that can be used on
any object as per July 24 meeting notes . It led the decision to remove
the iterate trap on proxies :
"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
Proxies that want to redefine the behavior of for-in loop can just decide
to return a different iterator than the target one.
