## Agenda

- [@mjcarroll] Lyrical Features
  - I would like to do a round of status updates on Lyrical roadmap features next week

  - **Goal:** make ROS 2 C++ messages more “introspectable” at compile-time. Currently, C++ messages don’t easily expose how many members they have (arity) or what those members are named without using external reflection libraries or complex trait
  - **Action:** Looking for reviews/feedback/input
