I'd be grateful if someone could explain how a template class can have
nested template friends.

Given the following pair of templates:

    template<typename T1> class A {
        template<typename T2> class B { };

        // template<...> friend class B<...> ??
    };

How can I make all specializations of template A::B friends of A<T1>? I've
searched the December 96 draft (11.4, 14.5.3 and 14.6.5) and it seems it
can't be done at all. Would anybody know the correct syntax for the friend
declaration?
