Why not just - `$$('label[for]')`?

Executing `$(l.readAttribute('for'))` more than once seems
unnecessary. Why not save it in a variable?

You can't really track "focused" elements using native DOM methods.
Instead, you can observe all of the elements for focus/blur events and
"mark" them as "focused" accordingly. You can then check which element
is currently focused right before submitting a form.
