Feedback during the second review was light but positive. The Language Steering Group agrees with the proposal author that the subset of body macros described by the revised proposal is a valuable feature on its own, with future work devising structured solutions for composing multiple body macros and simplifying common tasks like wrapping function bodies. Therefore, we have accepted this proposal.
Thanks to everybody who participated in the reviews!
I’m glad such a flexible macro role was introduced. I only hope that in the future we get more granular function body macros that tell the compiler what names they’ll be introducing/removing so that the original body can be type checked. I imagine debugging compiler errors with the current feature will be pretty challenging. Especially when not using Xcode which is one of the few IDEs with convenient inline macro-expansion functionality.
