[Macros] Allow reporting diagnostics on class keywords/identifiers #55718

Open rrousselGit opened 4 months ago

rrousselGit commented 4 months ago

Hello!

I'm currently experimenting with macros ; in particular error handling. At the moment, we seem to have the ability to report warnings/errors on the class name, which is awesome. But in some cases, it may make more sense to show the warning in a slightly different location, such as on class keywords.

In particular, I'd like to show an error on the abstract keyword, because my macro requires a non-abstract classes.

Although I can currently show an error on the class name, it would be more developer friendly to show the error on the abstract instead

Thanks! This is useful to keep track of but not high priority right now, so moving to the backlog.
