I'm hesitant to add that (I've definitely thought about it, in the past)
because .valueOf() doesn't cover all comparison cases.
obj > obj2 works (as you noted)
but if ( obj ) {} doesn't (it always returns true)
Additionally, in Firebug, the result shows up as a number rather than
something more useful (like a list of elements).
