Well, only if you view things that are new as additions to what is  
there.

I prefer to see new things as generalizations or refactorings of what  
is there.

In Arches, I view message sends as a special-case of connectors.  So  
things like := or => or possibly ;; can also just be connectors, but  
ones that are not message sends.

Admittedly, I haven't yet thought wether I can make statement  
separators into connectors.  Superficially, it doesn't look like they  
wouldn't be:  they connect statements (at the same time separating  
them ;-)...
