Actually, whatever token is used, it should NOT be one that would be a legal message selector. It's new syntax, and messages and syntax should be distinct.
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 ;-)...
