Looks promising, and super job on the presentation.

Once you have it working, give some thought to using a special purpose
allocator for the elements of your container.   A memory pool scheme,
anchored on the container, might pay dividends if it removes the size test
for element allocations.  If you want the pool anchored on the container,
then overloading operator new is not best, but rather have a container
function do the allocations of its elements (from a pool it owns.)  Such
anchoring of pool in container is a separate decision from deciding to use
a fixed block allocator at all.  The fixed block allocator will be worth it
regardless of where the pool lives.  If you have to move elements from one
container to another, then anchoring the pool on the container is not
appropriate.  But you could then have a class that held all your containers
and a pool common to those containers.  I bring this up because when
instantiating hundreds of thousands of elements, memory heap calls can be
the bottleneck.


Since you probably want the pool anchored on the container
