[@xealit]

wait, did he actually show how to _define_ a hidden the overload? It seems like a slide is missing there, it's just a friend declaration. Probably he meant to also define it there: struct T { friend std::ostream& operator

Same goes for the insertion operator; but the functions are normally defined elsewhere (in the impl. files).
