I read all that three times and I still don't understand what makes this better than just using a deque.

Probably because it's written to be read 10 times without saying much...

In the current implementation: smaller sizeof(), slightly better performance (due to fewer checks, not handling the "front" case), and better memory usage (deque uses a "move-to-middle" strategy when resizing the index).

Thanks. Speaking of move to middle, on an entirely unrelated note, do we have an implementation of move-to-middle vector-based deque?
