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 ;-)...

Answer:  they are all connectors.

The pipe I have in mind perfectly blends with "messaging" ... because it's just sending a message to the return value of the previous method. Not only.

IMHO, pipe blends even better with "connecting"...


yep ... connecting better ....
