I agree, this is a problem, and I don't know any good general solution to it. It can comes up in two different ways: typedefs and template type parameters. The best solution I know of involves adding a construct to the language which could be used to check whether or not two types are the same, which can be used to supress one of the two competing definitions when they are. However, even that approach has its problems. > Nicola Musatti's suggestion would be a better solution. But it doesn't solve the problem, it just moves it. It just means that you won't have the problem with int*, but you will still have it with whichever other type std::vector::iterator is a typedef for. --- [ comp.std.c++ is moderated.
