Looks good, for the branch too - the problem is just that the overload 
at issue belongs to _Insert_base thus it can't just forward, it doesn't 
see the overloads taking rvalues. Can we do a quick audit of the other 
containers and see which are already Ok, which in case can be fixed with 
moderate work?

Nit: let's use -std=gnu++11. And semantics, not semantic.
