expand: Feature gate AST-based attribute macros on expressions and statements Right now all of these macros happen to either be unstable or to produce errors when used on expressions and (non-item) statements, but it is safer to feature gate them anyway to avoid unexpected stability holes in the future, because all token-based macros are already feature-gated in these positions.
