Oh yes, people keep telling me array(char) wastes three bytes per
character and I keep forgetting. Sorry.

So... what is the recommended way of approaching specialisations like
this, where particular_container(T) can be implemented easily in terms of
generalised_container(T), but for particular instances of T people wish to
use different implementations? Or perhaps I should stop muttering and just
do it...
