r=me with the comment and maybe some squashing. |
The other cases: `concat_idents!`, `log_syntax!`, and `trace_macros!`, (these macros, with `asm!`, are handled (eagerly) in feature_gate.rs).

boxand placement-in(#22181).This is fixing a bug, but since there might be code out there that is unknowingly taking advantage of that bug, I feel obligated to mark this as a:
