If I remember correctly, there was discussion at one point for creating a new built-in macro named
func!(), similar to
line!(). I can't find the original discussion now, and I have no idea what happened to the idea. Does anyone know what happened to the idea? Was it ever resolved, or did the discussion just fall away?
The only thing that I really remember was that there were concerns about how to deal with closures, but I don't remember anything else about it.
