You know what else ensures that quiet changes do NOT occur? Using 
the same version of the compiler. It also prevents you from 
having to choose between using compiler extensions or limiting 
yourself to functionality that didn't have the consensus of the 
committee. And when an updated standard comes out, which adds 
modules, you don't have to decide which "standard" you're using.
