No matter where you move the dependency information, there is still 
going to be some kind of human factor here.

To reiterate, we must resist the urge to do fancy things that make our 
(and not our users') life easier, as it costs us performance. The only 
way we are going to remain as fast as we are, is if we continue to push 
ourselves.

That said, I think we can do all kinds of error checking during build, 
which to me makes way more sense then any kind of runtime analysis (why 
continually verify what is known to be good?).
