The value of uniqueness lies in the fact that you can design

I think {keys, maps, values} (and the pivot to using Symbols and

BTW that was just one thought (from me), and TC39 went another way to
avoid the 'values'/with incompatibility found via Ext.js. (See the
meeting notes for the first day, about the @unscopeable list.)
Ah right, forgot about that. Another example (in the wild) is
SpiderMonkey's use of "iterator" for the iteration protocol.
In ES4 days it was __iterator__, after dunder-iter in Python.
More recently, Jason implemented 'iterator' for two reasons, I think: 1,
lack of symbol spec of implementation as prerequisite; 2, belief that a
public name was better. Jason argued that case here, but I don't think
he prevailed (Dean Landolt disagreed).
We aren't putting this out "in the wild" for use by anyone, it's just a
temporary state, which depends on symbol spec resolution for ES6 -- this
thread's topic!
