What are cases where it can be converted? Are you thinking something like
converting em to px? I don't think we should transparently do conversions
like this. It would make sense if you had something like
element.computedStyle.margin.l[0].px, but for declared styles it seems like
we should throw. If we do decide to convert, there should at least be a
simple way to check if the value is set in px, em, whatever without
resorting to string parsing.
