It's not just my sample application; quite a few grokkerdam sprinters
worked on it. Anyway, I don't expect the introduction of actual
templates will make it harder to understand.

Good question. This is an area that we have been thinking about. I think
it might be reasonable to have Container.set also try to add the object
to the session directly. They are two operations though: adding an
object to the relational database and changing the record so it's added
to the container.
In the ZODB story attaching a persistent object to another one (like
adding it to a container) causes it to be persisted, but in the RDB
situation these are considered to be separate operations.
