Where possible we absolutely should not be.

Making things crash at runtime, because the compiler did not apply the 
knowledge it has is just ridiculous.

Imagine going to ``http://google.com/itsacrash`` and crashing Google.

Or pressing a button too fast on an airplane and suddenly the fuel pumps 
turn off and then refuse to turn back on.

Instead of the compiler catching clearly bad logic that it has a full 
understanding of, you're disrupting service and making people lose 
money. This is not a good thing.
