That'd be useless, even assuming a hypothetical Utility that doesn't depend 
on the world as it does now. It would make Utility depend on Exception 
(because throw_exception.hpp does depend on Exception), thereby not saving a 
dependency, but introducing one extra.

This kind of reaction is understandable but misguided. Exception's author 
(Emil Dotchevski) likes dependencies much less than most people and the 
library is relatively self-contained (and I would expect it to become more 
so as we transition to the new structure). It's other modules you should be 
afraid of, not Exception.
