In the following example:
template<typename G, template<typename H> class I = B>
class J;
template<typename C, template<typename D> class E>
class F {
template<typename G, template<typename H> class I = B>
friend
class J;
template<typename K, template<typename L> class M = B>
friend
class N;
friend
class O;
J<int, B>* j;
N<int, B>* n;
O* o;
};
int main() {
return 0;
}
N appears to not be recognized as a template (in the declaration of n) based on its declaration as a template friend, whereas exactly the same declaration with an additional declaration in file scope is acceptable (template class J, declaring j), as is a friend declaration of a plain class. The c++ rules in this area are incomprehensible to me, but admitting friend declarations in one case and not the other seems unreasonable if not incorrect.
