There are a couple of things that I would think should be permitted by the
definition which might not be apparent.

An archive which would be used for logging. I toyed with this but it turned
out not to be trivial as I had anticipated. Basically I enviaged an archive
that would would not do any tracking regardless of any serialization traits.
This would be usable for things like transaction commit/rollback. Its still
speculative but I don't see that the Archive Concept as envisioned prohibits
it. Also for debug logging perhaps. Finally an application for write only
memory !!!.

Since Archive is dependent upon Serializable, I'm wondering if the sequence
of these two sections in the documentation shouldn't be switched. Hmmmm.

Anyway, thanks for looking into this. Take your time. I'm still thinking
about two-phase lookup
