It bugs me that I can't just do `document.querySelectorAll(...).map(...)` even in Firefox 3.6, and I still can't find an answer, so I thought I'd cross-post on SO the question from this blog:

<http://blowery.org/2008/08/29/yay-for-queryselectorall-boo-for-staticnodelist/>

Does anyone know of a technical reason why you don't get an Array? Or why a StaticNodeList doesn't inherit from an Array in such a way that you could use `map`, `concat`, etc?

(BTW if it's just one function you want, you can do something like `NodeList.prototype.map = Array.prototype.map;`...but again, why is this functionality (intentionally?) blocked in the first place?)
