I cannot get this compiled with g++ v 2.95 friend ostream& operator<<(ostream &os, const any &rhs) { return os << *any_cast<bool>(rhs); }

What's the intent of using the word "friend" here? I think that might be the problem. You can declare this function without "friend".

I have tried without the friend declaration but it does not help.... Anyway, can you think of any general solution, I mean without specifying a list of ValueType ? Sincerely, Patrick
