    Making DOM lists behave more like Arrays

    Primary intention would be sorting. Ultimately, in-place modification of the list requires setters for the items in it. A NodeList doesn't have setters, but an HTMLOptionsCollection does.

    An example of this is here:

    Notice the issues associating with shifting and unshifting. I have a few theories on why it can pop and push but not shift and unshift, but nothing I feel comfortable putting my voice behind yet.

    Gecko-only, btw. As always. Just some food for thought mainly.

    Implications of this:
    • Anything that provides Array index-like accessors can use Array methods
    • But only collections with setters on individual items can be modified in place (sorting, popping, etc)
