I for one sometimes wish there was...

Of course, sometimes you purposely write code which you know is going to 
overflow and wrap round in a specific way. But frequently you *don't* 
want this behaviour - and I wish there were some pragma or something to 
make this be checked. AFAIK, most CPU types give you an efficient way to 
testing for such conditions...
