Well, so much for the theory that Marin understands
'Version but wants different behavior :-)

Marin, you persist in thinking that unit'Version is about
the version of the unit in question. Perhaps we should have
called the attribute something else, since the name sure is
confusing you. Version here does NOT mean the source
version of the unit in question, it means the *object*
version of the unit, which includes contributions from
all the units on which the unit depends.

So the notion of newer or older is simply and fundamentally
inapplicable, given that this version represents the state
of a *set* of files.

I trust this makes things clear, if not I give up :-)
