I'll have to digest your and Michael msgs and check all ends first before I
can reply in any sane way.

Till now, I fixed that routine also in a drive-by style, so it is time to
really dig into it and make sure there are no problems. However this weekend
is 2.4.2rc1 building, so it will probably be after.

I was more thinking about e.g.  

identifier unitname.something
and unit unitname_something

clashing.

Of course dotted unit names will become a problem in time too.

Well, there is no example needed if it is a fundamental problem. Underscore
is a legal identifier character, so using it as separate can introduce
clashes. As said, dotted unit names will be a can of worms too.

On the other hand, if there are no current problems, then at least it is not
acute.
