If you suppress checks, basically the behavior of all programs are 
unspecified. Thus, I highly recommend that you don't do that. (Consider 
Suppress similar to Unchecked_Conversion -- OK when used in the right hands, 
dangerous otherwise.)

If you *don't* suppress checks, the behavior is well-defined. So what?
