just stop thinking in C/C++ "#include" terms. there, you have no other ways 
to restrict data access, so they were forced to make it broken, and then 
introduce "friends" just to workaround the fact that there are no modules 
in C++.

instead, start thinking with modules in mind. module is THE unit of 
incapsulation. there is nothing wrong in isolating class or two in a 
module. then, to make imports manageable, either create a package of that, 
or just a dummy module that does `public import xxx;` for everything.
