Doesn't `with` have significant runtime costs? I didn't think people didn't like that one because it was a 'bad pattern' - I thought it was because it was really slow.

EDIT: I went ahead and JSPerf'd it, and it is 13x slower to run the example in the article.

A lot of times this doesn't matter, but it's not nothing.

Edit 2: Also people avoid using `with` so their minification tools have a better chance. Another thing that can be overcome, but just pointing out that it's not religious dogma that makes people avoid `with`.
