This do not work. I think it is a bug but I see how could see 
it as a feature. Which one is it ?

It seems like a feature to me. Otherwise, you would have A.foo, 
which is in module a, calling a private function from module b. I 
think it is sane that the function should be public if you want 
to do things such as this. Furthermore, it will stop you from 
accidentally passing private symbols to alias template arguments 
when you don't mean to.
