We need an implementation of ArrayBuffer.isView, added to the ECMA specification as of the May 14, 2013 draft:

15.13.5.4.2 ArrayBuffer.isView ( arg )
The isView function takes one argument arg, and performs the following steps are taken:
1. If Type(arg) is not Object, return false.
2. If arg is an exotic Array object, then return true.
3. If arg has a [[ViewedArrayBuffer]] internal data property, then return true.
4. Return false.

This is needed to fully comply with WebGL requirements.
