My concern is that there will be situations which no one can predict; 
exceptions are very hairy (after all, they can go up the chain of 
functions not written in D).

This is why I'm not suggesting that we should replace exception handling 
in the general case. Only where the compiler can see that it can be done 
(plus this can be improved over time).
