I prefer the distinction for the application of corresponding metavariables.

Would it be more helpful to mention the movement of the ampersand
before SmPL disjunctions?

Can the following SmPL code variant ever become more attractive?

+virtual context, report, org


…

How do you think about the following SmPL code variant?

+expression subE1 <= as.E1,
+           subE2 <= as.E2,
+           as.E1, as.E2, E3;


…

Please omit the extra Python variable “msg” for the passing of such simple message objects.

What does hinder you to take the proposed script variants better into account?

Regards,
Markus
