Ok. But I would be more interrested in pratiacal approach. So my questions 
would be:

1. Which tasks require fusion::vector and does not accept vector<variant>?
2. Which tasks require vector<variant> and does not accept fusion::vector?
3. Which tasks I could prefer fusion::vector for? What practical reasons? 
And if this is performance what is a performance advantage 1%, 10%, 50%?
4. Could you compare from usdabiltiy standpoing all the operation shared by 
this two approaches?
