Hi,

I like a nidea presented, but I am not sure that implementation is 
portable. As far as I remember following friend declaration is ill-
formed:

template<class T>
class A {
    friend class T;
};

I do not have an access to Standart and can't find information online 
(other than 
http://www.prismtk.de/docs/software/cseq/cxxdontpanic_76.html#SEC76), 
so I would like to here a word from expert in this area. Anyway MSVC 
does not compile your example.
  If we would be able to find portable solution I will vote for 
adding this cool classes into utility section. I would also add more 
argument(s) to be able to specify additional "freind" classes.

Regards,

Gennadiy.
