I read this the other way around. Views.View is an extension of Stores.Store.

I do have a model that I store/load in my "Ants" program. It was the
other choice for me to move to 1.6 when I gave an example of releasing
a project. I wrote Ants in about 2000 under 1.4, and I remember
spending a lot of time with little understanding on
Stores.Store.Domain. It is likely that I did something that works
under a special circumstance, but is fundamentally incorrect.

I would have to go back and read my code, but my natural thinking is
that I stored only the Model, and re-create the view after the Model
is loaded. I remember distinct plans to display two radically
different views --- View A is the ants on the ground, View 1 is the
pheromone trails on the ground. I developed the project with the view
that any third party would write View 1 to demonstrate (Model View
separation) and effective coordination during development, so the
entire prospect of storing a view seems unlikely.

Today I have some justification for going through the ".eth"
converter. No promises. But are there some questions or scenarios
you would like me to have in mind? Would you be more interested for
me to review the .eth converter or the update to Ants?

(from 1.6-rc5)
