Overview

This is a value object that by default starts out life as not having decided what exactly it is.

On first adding another object, it assumes an internal form.

It will complain if its internal form does not correspond to the assumed external one, ie. when you want to << something, but it has already assumed the internal form of a hash (<< does not exist on a hash).
