I've been under the impression that such separation is for strong
exception guarantee. We can't popFront (and C++ cannot operator++)
before knowing that the copy of the returned value has not thrown an
exception.
The article you've linked does not even mention exceptions so perhaps
this concern is now historical? Or perhaps there are no types that throw
during copy anymore, meaning that they are either trivial bits or
reference types?
