Our implementation of TypedArrays implements the original specification [1] which has been superseded by the ECMAScript 6 specification. ES6 does specify that the TypedArray prototype has a @@iterator function in order to work with the ES6 iterator protocol and for-of loops [2].

[2] http://www.ecma-international.org/ecma-262/6.0/#sec-%typedarray%.prototype-@@iterator

Even though we do not fully support ES6 version of TypedArrays, we should implement the @@iterator function in order to make TypedArrays work with Iterators and for-of.
