Found http://yuiblog.com/blog/2006/09/26/for-in-intrigue/ , which was
what I was thinking about. There are a ton of comments on it, which tell
a little about what I was thinking about. However, I think in general
"Not confusing arrays and objects" would be the right thing to think of
this as, and the posts I was thinking about are about other issues.
