On reflection, I think the fact that the unneeded bounds checking can't be
turned off would probably dissuade me from using this. (I doubt any
compiler is going to be smart enough to realize the bounds check following
the modulus is unnecessary).

Too bad circular-buffer doesn't allow turning off the checking (via a
template parameter).
