My main issue with that VersionDict is that after I did it, I didn't
had a real case
where to use it. So, it never been used beyond the unit tests and some
playing around.
(I wrote it when dicts in Python got versioning and that was only
visible from the C-API)

I remember the idea for the versioned value retrieved occurred to me
quite naturally when I wrote it,
so it is probably close to the "OOWTDI".
