You can just do `if (Symbol.iterator in potentialIterable)`.
Does that work cross-frame?

Depends upon what you mean by Array detection. If you mean is obj an
exotic array object (ie, an object that automatically updates the length
property value as integer indexed properties are added or deleted) then
Array.isArray(obj) detects exactly that.
Okay cool. Is there merit in

I wonder if by any chance this could sneak into ES6 ... we have only
singular version here:
https://people.mozilla.org/~jorendorff/es6-draft.html#sec-object.getownpropertydescriptor
**rationale**
The easiest way to create a shallow copy of a generic object could be:
```javascript
var shallowCopy
Further rational:
* Symmetry with defineProperty/defineProperties.
* One of the benefits of defineProperties (and create) is that they handle
errors such that the failure of any individual property doesn't necessarily
fail all the remaining ones. It is, of course, possible for a developer to
actually, since `Object.getOwnPropertyDescriptor` accepts `Symbols` too as
second argument, the equivalent with current ES6 would be even more prolix
than that
```javascript
var shallowCopy = Object.create(
Object.getPrototypeOf(originalObject),
Brandon I take your answer as +1, thanks.
I've also gisted a possible/basic polyfill here:

What is an example of a use case where one would choose to use Array.of

Here is one case where literal array syntax is not possible:
class ImprovedArray extends Array {
