To me, this visually looks better than @annotation, but feels overly narrow/
restricted.

It covers classes, but, for example, P3294 also talks about
    consteval { property("author", ^std::string); }
which could also benefit from a similar syntax sugar to become
    @property std::string title;
where the (things...) syntax would not be easily applied.

I haven't followed this closely (was away for a long time), so I might be
missing something.
