The requested form isn't exactly "do nothing", it's "wrap and overwrite". If
that's implicit in the (to my mind over-) general concept, then that's fine.

I have to admit that I still don't see the point of the resizing versions -
if you want something that allows you to add entries indefinitely, why not
use one of the existing library classes (say, deque)? As far as I can see,
the ONLY POINT to circularity is the overwriting property (for all sorts of
MRU-type lists).
