The fact that it doesn't do dynamic allocation can be a big performance
advantage of fixing the capacity, depending on the application of course.

A similar class that would be of use to me is a fixed capacity deque
that did no allocation, but just used an array as a circular queue.
I've actually written a class that did this, but I only wrote enough to
satisfy my needs, it's far from being a complete container.
