Compilation extremely slow since macros adoption

I’m sorry if my response gave the wrong impression. I do not personally work on the macros feature, and I have not been following this thread for the last few months.

The LSG is aware that there are build-system issues causing a lot of pain for macro adopters and their downstreams. From an abstract language perspective, I don’t think any of those problems are particularly challenging to the point of requiring an overall design change to macros; the project just needs to put in the work to fix them. I can’t tell you when that will happen, though, which I know is not a satisfying answer.
