I know that a lot of consideration is being given to syntax à la Honu, but I’m also curious about what kind of changes to the macro system are being considered. Are there currently any such ideas being discussed?

the surface syntax changes were being considered more than changes to the core macro system

most discussion has been on surface syntax and core libraries

issues and pull requests at the github repo are where most discussion has taken place https://github.com/racket/rhombus-brainstorming/\|https://github.com/racket/rhombus-brainstorming/
