[Bug c++/15695] New: Instantiations of a template cannot be mutual friends?

["igodard at pacbell dot net" <gcc-bugzilla at gcc dot gnu dot org>]

template<typename T> class A;

template<typename T> class A {
public:
    template<typename R>
    friend class A<R>;
    };

int main() {
    return 0;
    }

gets:
~/ootbc/common/test/src$ g++ foo.cc
foo.cc:6: error: partial specialization `A<R>' declared `friend'

Is this a bug, a hole in the language, or are you supposed to declare mutual friendship some other way?
