Why? And you say "False", so evidently, the commented trait will try to 
instantiatie rv.

And the bad part is that is_enum requires instantiation, which breaks 
the possibility of recursive containers. And I don't want that to 
happen. Is there any possibility to detect an enum without instantiating 
the class?

Best,
