I personally still like the syntax Henning proposed over 10 years ago
(with a little tweak by me: please read the entire thread):

There was a prototype patch posted by Henning:

I doubt it applies cleanly any more, and there's still a good bit of
work (most particularly, we need a set of at least semi-comprehensive
regression/unit tests for the new feature), but it's a starting point.
