I'm out of my depth here, but the fact you use inheritance means the 
two types are not the
same as a consequence, right? I.e. std::is_name is false?
Correct, these are diferent types.
...
And I suppose such partial specialization is not possible with template type
aliases to have is_same<> being true? Not sure it matters, just thinking out loud.
No, template aliases don't support partial specialization. But I don't 
see any fundamental
problem with subclassing.
