Thanks but you're giving me way too much credit. I think it's a straight
policy passed as a template argument. Then the policy has two
implementations: one that uses straight allocation and one that uses dynamic
allocation. The functions for dynamic growth will return errors or will not
compile at all (if called) for the non-dynamic implementation. It's that
easy.
