I don't think that's a very good idea. If we need this, which I doubt, it should be something like a new __undefined__ keyword, that expands to an undefined value. In C++, a syntax like __undefined__<X>() would be plausible; I'm not sure there's a good C syntax. Perhaps you could do what tgmath does. I guess if you had this, you could use it in place of the attribute; int i = __undefined__<int>(); would serve to indicate that you were knowingly not initializing i. -- Mark Mitchell CodeSourcery m...@codesourcery.com (650) 331-3385 x713
