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 ;-)...
