This is a terrible idea. You're changing the fundamental interface of language primitives. This is a terrible idea. Having T and U behave differently when you define T* and U* is going to bring about so many errors it's not even funny, and std::pointerto is terrible. When you say "You can work around it like unary operator&", this isn't a *good* thing, it's a terrible, terrible thing. The problems experienced with that operator clearly show how overloading something like this should never be done. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
