As long as you're using a templated function and thus can use IFTI (implicit function template instantation) instead of giving the template arguments explicitly, you don't have to put the template parameters with default arguments last. You'd just have to put it after the variadic parameter if you intended to give the template arguments explicitly. So, as long as you don't have to give the template arguments explicitly, you're fine. If you need to give them explicitly though, I think that you're stuck. - Jonathan M Davis
