Don't use for(var x in y)

It would be great if you could remove all for(... in ...) loops from your javascript files and replace them by normal for(i=...;...;i++) loops. I know they work fine usually, but when you are using a library that extends the Object object (for example prototype), the loop returns several methods in addition to the array's items, which breaks several functions.
