Array.isArray should return true for an `observableArray` about tko

[mbest]

Observables already have Function at the end of the prototype chain.

Thanks @mbest - I think we will have to experiment with an array instance as an intermediary on the prototype chain, if it can't go at the end ...

Here is a good summary of the options: http://perfectionkills.com/how-ecmascript-5-still-does-not-allow-to-subclass-an-array/

... though we probably have a thousand other higher priority items right now. 😁

@brianmhunt I believe what you want to do is indeed impossible to achieve for the reason @mbest mentioned. At least at the current state of JS.

You can make observableArray iterable though.

Closing this as impossible. Noting that observableArray is now iterable for tko.
