> Much of the classification capabilities relies on parsing values out from the
> Text object just to determine what type of "thing" is being used. We should
> try to avoid having to do string manipulation for this kind of thing and
> instead encapsulate it in Writable instances. This should make things
> perform faster and bring stronger typing to the problem, which should make it
> easier to understand and debug the code.
