My guess is that if we changed the behavior of `-release`, D 
programmers would learn the new convention pretty quickly.

Even if they didn't, though, the change is fail-safe--it will not 
break any code that isn't already broken in debug builds. So as 
compiler changes go, this one is relatively low-risk.
