For clarity: I am not against this dot by itself. I can only assure you, if
implemented, that it will not end up in 2.2.2.

As for implementing this feature: this is not so trivial as one might think.

1. The parser needs changing. That's probably the easy part.

2. Symbol lookups need changing. This is the hard part, because you must be
   able to handle correctly unitname.identifier.identifier2.identifier3

   It doesn't take a lot of intelligence to see that if unitname can
   containe one (or more) dots, this mechanism becomes suddenly a lot harder
   because your unitname may, by accident, match unitname.identifier1 of
   a symbol in another unit.

And doing all this in a way that doesn't change current behaviour...
Not something you can do in a day, if you ask me.
