39. [tiny] local class and friendship

Section: 11.3 [class.friend] Status: NAD Submitter: Gabriel Dos Reis Opened: 2012-11-10 Last modified: 2013-03-09

Discussion:

When we went from C++98 to C++03 we made nested classes implicitly friend of their enclosing classes. We seem to have missed doing the same for local classes defined at member functions scopes.

Mike Miller explained:

Hmm. I think that's already covered by 11p2:

    A member of a class can also access all the names to which the class
    has access.  A local class of a member function may access the same
    names that the member function itself may access.

By the definition of "private" in 11p1, a nested class has access to the private members of the containing class; a member function of the nested class therefore also has access to the private members of the containing class; a local class of such a member function has the same access as the member function; and a member function of the local class has the same access as the local class, the same access as the containing member function, and the same access as the nested class.
