See, this is a good reason why "()" vs "no ()" should be dictated by the 
API, not the caller. Under the current system, there's nothing preventing 
someone from writing an "is this range empty?" check that seems to work on 
one range, but then fails to compile on any range that chooses to implement 
"empty" as in your example above.
