Iterables are useful not only in for/of loops but also in otherwise
polyfillable constructs; for example, in the Set constructor:
// Let `a` be a Set object
b = new Set(a) // copy the elements of `a` into a new Set
Question: Will there be a standard way for obtaining the @@iterator

better exposed through this layer of faux-stratification rather than
completely unstratified, due to its primary use in supporting syntax

From: Claude Pache
implement/polyfill the iteration protocol in both old and new environments,
using `GetIteratorSymbol()` where @@iterator is needed. If that
`GetIteratorSymbol()` function is readily available in a standard place, it
will allow different libraries to cooperate.
I think

Sure. Polymorphism, therefore a method.

How is this different from toString?

Hi,
One very useful feature in RequireJS is the ability to hook into the
dependency tree through the onResourceLoad API.
Currently, the way the link function is designed for ES6 modules, there is
no way for a loader to discover the imports for a given module.
If there was some way to allow some
Excellent, great work. From private correspondence with Sencha, it seems
they may be able to avoid the problem without too much trouble.
Still, a bitter stab in the back from 'with'! And cautionary for future
method additions (not that I propose mangled or unlikely names).
