[Feedback appreciated] Sandboxed Localstorage for views

This is a potentially very powerful feature, powerful enough to deprecate the bug-prone `$params` and enable many more different use cases while staying secure.

I wrote a draft of a couple of ideas on this. Please check it out and share your ideas. Thanks! https://github.com/Jasonette/documentation/issues/56

p.s.
I'm posting here just so that more people can see this. Please comment on the linked thread.

Start with the linked Jasonette documentation issue, which contains the draft ideas and is the requested discussion thread. No implementation files, tests, entry points, or acceptance criteria are identified here, so the work is not ready to begin or verify from this issue alone.
