Alright, I guess I would want to access the underlying buffer 
regardless of whether the container is indexable or not...

Although, an optimization protocol probably should let you query 
whether elements can be out of order. And possibly also test 
whether an element is present or not.

Then you could allow direct access to the buffer of a simple hash 
table or priority queue etc.

Hm. Interesting topic.
