If that's how C++ works in the official spec, it's not how it works in 
real life.

I've got half a million lines of code in Unreal Tournament 2003 that 
this "feature" breaks, which compile fine on everything from CodeWarrior 
to Intel's compiler to Visual C to GCC 2.95.3, 3.1, and 3.2. I can list 
at least five other games I've worked on that this breaks. I do not 
control or write this code, I just port it.

Surely there's got to be some consideration for backwards compatibility, 
if not real world issues?
