According to g++ and comeau, the following is illegal: (The commented line
allows the code to compile.)
class A {
public:
A () {}
~A () {}
private:
class Nested;
//friend class B;
};
class B {
public:
B () {}
~B () {}
private:
friend class A::Nested;
};
Here's why:
"7 A name nominated by a friend declaration shall be accessible in the scope
of the class containing the friend declaration."
It is ridiculous that I can't give access to an inaccessible class. You have
to have access to be able to give it? What is the justification for this?
