Aah of course; By reading the source code of the children function I figured the array of elements returned was appended to the parent element. The strange thing was that it was also adding them to `el` object but indeed it appears this is done to maintain a reference to the children so they can be modified later (which I would have seen had i read the example a bit more carefully :S )

I'm still not sure how I feel about that bit of code though but it sure is clever...
