knockout js ko.toJSON not working in IE7

Question

Is this a knockout bug?

<h2>Debugging Variables</h2>
<div data-bind="text: ko.toJSON($root, null, 2)">
</div>

I get the following error when viewing my page in compatability mode:

Microsoft JScript runtime error: Unable to parse bindings. Message: [object Error]; Bindings value: text: ko.toJSON($root, null, 2)

Works fine when compatability mode is off.

ko.toJSON uses the JSON.stringify method internally which is not implemented in IE7.

So if you want to support IE7 you need to include a JSON.stringify implementation like

Douglas Crockford's JSON2 parser (you need the json2.js file)
