Here is a template class.

template <typename T>
class XXX
{
    friend class AAA<T>;
    template <typename S> friend class BBB<S>;    // It will be illegal
code
};

------------ about AAA ----------
Class AAA<int> is a friend of XXX<int>.
Class AAA<char> is a friend of XXX<char>
But
    AAA<char> is not a friend of XXX<int>
    AAA<int> is not a friend of XXX<char>

It's OK, it is what I want.
--------------------------------

------------ about BBB-------------
I want BBB<S> (for any S) to be a friend of AAA<T> (for any T)

For example
Class BBB<int> is a friend of XXX<int>
Class BBB<char> is a friend of XXX<char>
And
    Class BBB<char> is a friend of XXX<int>
    Class BBB<int> is a friend of XXX<char>

Will it be impossible?
