I have to agree. However, having had to deal with C++'s excuse for exceptions 
(and the effects of C programmers being let loose on them), I can understand 
where he is coming from.

And the basic idea of flow control you can't see being a potential problem is 
sound. For exceptions in general, the benefits are worth the costs, but I don't 
think the same can be said for allowing statement templates the power to 
suppress them.

Cheers,
Nick.
