Hmm, okay that certainly seems like a step backwards since we often talk about macro_rules hygiene (imperfect though it is) as avoiding one of the mistakes of C macros. But yeah that makes sense why we don't want to have expression macros yet!
I get that but I worry about trumpeting "Macros 1.2" with so many caveats (you'll get name resolution conflicts, you can't use them in functions, concat_idents! still doesn't work, etc).
