The problem is that at least in my environments - with any browser I use - arrays are not that simple and *do* have prototypes, so the seemingly nice (and Javaish/Pythonish) syntax `for (x in coll)` picks up a lot of "garbage." So, we need to use ugly indexed loops to only pick up the elements in the array.
